[PATCH 05/29] ixgbe/base: fix checksum error of checking PHY token

[Beilei Xing]

This patch sets the Host Interface PHY token command
checksum to the checksum default of 0xFF, therefore
the checksum is not checked by the firmware. Otherwise
the command fails with a checksum failed error.

Fixes: 86b8fb293fdf ("ixgbe/base: add sw-firmware sync for resource sharing")

[PATCH 09/29] ixgbe/base: add link mac setup for x550a SFP+

[Beilei Xing]

This patch updates ixgbe_setup_mac_link_sfp_x550a for x550 SFP+.
ixgbe_set_lan_id_multi_port_pcie has been updated to set the MAC
instance(0/1) which is needed when configuring the external PHY,
since x550a has two instances of MGPK. The MAC instance is read
from the EEPROM.

[PATCH 10/29] ixgbe/base: clear stale pool mappings

[Beilei Xing]

This patch adds clearing the pool mappings when configuring default
MAC addresses for the interface. Without this there will be the risk
of leaking an address into pool 0 which really belongs to VF 0 when
SR-IOV is enabled.

[PATCH 17/29] ixgbe/base: change device IDs

[Beilei Xing]

There're two device IDs changed from 15C6/15C7 to 15E4/15E5 cause
PHY info changes. Make the change and use 15C6/15C7 for the backplane
SGMII. Clean up some discovery kludges from the previous shared ID,
and also add 15C6/15C7 to ixgbe_set_mdio_speed just for paranoia
to control MDIO speed even though nothing should be attached.

[PATCH 18/29] ixgbe/base: update swfw semaphore function

[Beilei Xing]

For X540 and forward it is possible if a system reset occur at the
right time to leave the SWFW semaphore high. This new function will
attempt to grab and release the semaphore. If the grab times out it
will still release the semaphore placing it in a known good state.
The idea is to call this when you know no one should be holding the
semaphore (i.e. probe time)
This patch alse fixes possible race issue between ports when issuing
host interface command by acquiring/releasing the management host
interface semaphore in ixgbe_host_interface_command.

[PATCH 20/29] ixgbe/base: limit PHY token accessing to MDIO only

[Beilei Xing]

This patch limits getting and putting the PHY Token to PHY MDIO
access only by adding ixgbe_read_phy_reg_x550a and
ixgbe_write_phy_reg_x550a. The PHY Token is only needed to
synchronize access to the MDIO shared between the two MAC instance.

[PATCH 21/29] ixgbe/base: smplify add/remove VLANs

[Beilei Xing]

This patch simplifies the adding and removing VLANs from
VFTA/VLVF/VLVFB registers. The logic to determine registers has
been simplified to (vid / 32) and (1 - vid / 32). Many conditional
paths and checks are no longer needed with this patch.

[PATCH 22/29] ixgbe/base: add bypassing VLVF

[Beilei Xing]

This patch adds support for the VLVF to be bypassed when adding or
removing a VFTA entry.  The PF can utilize the default pool while
preserving the VLVF for the VFs use.
Meanwhile, update corresponding VF ops and drivers where corresponding
ops is invoked.

[PATCH 24/29] ixgbe/base: use u8 to replace u16 for a variable

[Beilei Xing]

Since PCIe standard defines maximum of 8 functions per device lan_id
is a value 0..7. Because of that, lan_id don't need to be u16.

[PATCH 26/29] ixgbe/base: allow setting mac anti spoofing per vf

[Beilei Xing]

Make ixgbe_set_mac_anti_spoofing() consistent with the other
functions that deal with setting VLAN and Ethertype spoofing by
changing the prototype to accept a VF parameter.

Also change the logic for writing the PFVFSPOOF register to be similar
to the MAC and Ethertype functions.

[PATCH 27/29] ixgbe/base: add flow control autoneg for x550a

[Beilei Xing]

This patch adds x550a flow control auto negotiation support.
ixgbe_setup_fc_x550a and ixgbe_fc_autoneg_X550a functions where
added to setup and enable flow control. MAC ops function pointer
fc_autoneg was added so that hardware specific fc autoneg functions
can be called from ixgbe_fc_enable_generic.

Is it possible that these lines related to the patch 7:
[PATCH 07/29] ixgbe/base: change access method

It looks like first changes ops from ..x550a to ...x550 here and in
patch 7, using ops function instead fixed one.

Also if there is more details about ..x550a to ...x550 change it can be
good to add patch 7 comment.

Does it make sense to separate this patch into two.

One add ixgbe_init_swfw_semaphore related code (init_swfw_sync,
ixgbe_init_swfw_sync_X540)

Second is fix in ixgbe_host_interface_command, they are unrelated as far
as I can see.

[PATCH v2 05/30] ixgbe/base: fix checksum error of checking PHY token

[Beilei Xing]

This patch sets the Host Interface PHY token command
checksum to the checksum default of 0xFF, therefore
the checksum is not checked by the firmware. Otherwise
the command fails with a checksum failed error.

Fixes: 86b8fb293fdf ("ixgbe/base: add sw-firmware sync for resource sharing")

[PATCH v2 09/30] ixgbe/base: add link mac setup for x550a SFP+

[Beilei Xing]

This patch updates ixgbe_setup_mac_link_sfp_x550a for x550 SFP+.
ixgbe_set_lan_id_multi_port_pcie has been updated to set the MAC
instance(0/1) which is needed when configuring the external PHY,
since x550a has two instances of MGPK. The MAC instance is read
from the EEPROM.

[PATCH v2 10/30] ixgbe/base: clear stale pool mappings

[Beilei Xing]

This patch adds clearing the pool mappings when configuring default
MAC addresses for the interface. Without this there will be the risk
of leaking an address into pool 0 which really belongs to VF 0 when
SR-IOV is enabled.

[PATCH v2 12/30] ixgbe/base: fix error path to release lock

[Beilei Xing]

When there is an error getting the PHY token, the error path
fails to release the locks that it has taken. Release those
locks in that failure case.

Fixes: 86b8fb293fdf ("ixgbe/base: add sw-firmware sync for resource sharing)

[PATCH v2 17/30] ixgbe/base: change device IDs

[Beilei Xing]

There're two device IDs changed from 15C6/15C7 to 15E4/15E5 cause
PHY info changes. Make the change and use 15C6/15C7 for the backplane
SGMII. Clean up some discovery kludges from the previous shared ID,
and also add 15C6/15C7 to ixgbe_set_mdio_speed just for paranoia
to control MDIO speed even though nothing should be attached.

[PATCH v2 18/30] ixgbe/base: add function to reset swfw semaphore

[Beilei Xing]

For X540 and forward it is possible if a system reset occur at the
right time to leave the SWFW semaphore high. This new function will
attempt to grab and release the semaphore. If the grab times out it
will still release the semaphore placing it in a known good state.
The idea is to call this when you know no one should be holding the
semaphore (i.e. probe time).

[PATCH v2 21/30] ixgbe/base: limit PHY token accessing to MDIO only

[Beilei Xing]

This patch limits getting and putting the PHY Token to PHY MDIO
access only by adding ixgbe_read_phy_reg_x550a and
ixgbe_write_phy_reg_x550a. The PHY Token is only needed to
synchronize access to the MDIO shared between the two MAC instance.

[PATCH v2 22/30] ixgbe/base: simplify add/remove VLANs

[Beilei Xing]

This patch simplifies the adding and removing VLANs from
VFTA/VLVF/VLVFB registers. The logic to determine registers has
been simplified to (vid / 32) and (1 - vid / 32). Many conditional
paths and checks are no longer needed with this patch.

[PATCH v2 23/30] ixgbe/base: add bypassing VLVF

[Beilei Xing]

This patch adds support for the VLVF to be bypassed when adding or
removing a VFTA entry.  The PF can utilize the default pool while
preserving the VLVF for the VFs use.
Meanwhile, update corresponding VF ops and drivers where corresponding
ops is invoked.

[PATCH v2 25/30] ixgbe/base: use u8 to replace u16 for a variable

[Beilei Xing]

Since PCIe standard defines maximum of 8 functions per device lan_id
is a value 0..7. Because of that, lan_id don't need to be u16.

[PATCH v2 27/30] ixgbe/base: allow setting mac anti spoofing per vf

[Beilei Xing]

Make ixgbe_set_mac_anti_spoofing() consistent with the other
functions that deal with setting VLAN and Ethertype spoofing by
changing the prototype to accept a VF parameter.

Also change the logic for writing the PFVFSPOOF register to be similar
to the MAC and Ethertype functions.

[PATCH v2 28/30] ixgbe/base: add flow control autoneg for x550a

[Beilei Xing]

This patch adds x550a flow control auto negotiation support.
ixgbe_setup_fc_x550a and ixgbe_fc_autoneg_X550a functions where
added to setup and enable flow control. MAC ops function pointer
fc_autoneg was added so that hardware specific fc autoneg functions
can be called from ixgbe_fc_enable_generic.

[PATCH v2 29/30] ixgbe/base: define if enable crosstalk work around

[Beilei Xing]

A work around for a new crosstalk erratum that causes link flap in
entry cages has been introduced. So this patch defines the bit in
NVM that will tell software if this work around is needed.

Hi Beilei,

running check-git-log.sh scrip identified a few more issues in patch
subjects.

Can you please send a new version of patchset addressing following
issues, sorry for missing these at first review.

1) Unify "X550EM_A" usage in patch subject and commit messages.
        ixgbe/base: fix firmware commands on x550em_a
        ixgbe/base: add KR support for X550EM_A devices

"X550em_a" seems preferred in old commits.

2) Wrong headline lowercase:
        ixgbe/base: allow setting mac anti spoofing per vf
        ixgbe/base: add link mac setup for x550a SFP+
        ixgbe/base: add mac link setup for x550a SFP

mac and vf should be upercase

3) Line too long:
        Added support for the VLVF to be bypassed when adding/removing a
VFTA entry.

4) Wrong tag:
        Fixes: 86b8fb293fdf ("ixgbe/base: add sw-firmware sync for
resource sharing)

missing a " at the end.

Hi Ferruh,

Thanks for your careful review:)
After fixing some issues, there still exists warnings when running check-git-log.sh.
Can I ignore the two warnings?

1) Wrong headline format:
        ixgbe/base: fix firmware commands on X550em_a
        ixgbe/base: add KR support for X550em_a devices
Seems it's caused by '_' in name ' X550em_a '.

2) Line too long:
        Fixes: 36f43e8679ae ("ixgbe/base: refactor manageability block communication")
        Fixes: 86b8fb293fdf ("ixgbe/base: add sw-firmware sync for resource sharing on X550em_a")
Fixline shouldn't be separated into two lines, right?

[PATCH v3 05/30] ixgbe/base: fix checksum error of checking PHY token

[Beilei Xing]

This patch sets the Host Interface PHY token command
checksum to the checksum default of 0xFF, therefore
the checksum is not checked by the firmware. Otherwise
the command fails with a checksum failed error.

Fixes: 86b8fb293fdf ("ixgbe/base: add sw-firmware sync for resource sharing on X550em_a")

[PATCH v3 09/30] ixgbe/base: add link MAC setup for X550a SFP+

[Beilei Xing]

This patch updates ixgbe_setup_mac_link_sfp_x550a for X550 SFP+.
ixgbe_set_lan_id_multi_port_pcie has been updated to set the MAC
instance(0/1) which is needed when configuring the external PHY,
since X550a has two instances of MGPK. The MAC instance is read
from the EEPROM.

[PATCH v3 10/30] ixgbe/base: clear stale pool mappings

[Beilei Xing]

This patch adds clearing the pool mappings when configuring default
MAC addresses for the interface. Without this there will be the risk
of leaking an address into pool 0 which really belongs to VF 0 when
SR-IOV is enabled.

[PATCH v3 17/30] ixgbe/base: change device IDs

[Beilei Xing]

There're two device IDs changed from 15C6/15C7 to 15E4/15E5 cause
PHY info changes. Make the change and use 15C6/15C7 for the backplane
SGMII. Clean up some discovery kludges from the previous shared ID,
and also add 15C6/15C7 to ixgbe_set_mdio_speed just for paranoia
to control MDIO speed even though nothing should be attached.

[PATCH v3 18/30] ixgbe/base: add function to reset swfw semaphore

[Beilei Xing]

For X540 and forward it is possible if a system reset occur at the
right time to leave the SWFW semaphore high. This new function will
attempt to grab and release the semaphore. If the grab times out it
will still release the semaphore placing it in a known good state.
The idea is to call this when you know no one should be holding the
semaphore (i.e. probe time)

[PATCH v3 21/30] ixgbe/base: limit PHY token accessing to MDIO only

[Beilei Xing]

This patch limits getting and putting the PHY Token to PHY MDIO
access only by adding ixgbe_read_phy_reg_x550a and
ixgbe_write_phy_reg_x550a. The PHY Token is only needed to
synchronize access to the MDIO shared between the two MAC instance.

[PATCH v3 22/30] ixgbe/base: simplify add/remove VLANs

[Beilei Xing]

This patch simplifies the adding and removing VLANs from
VFTA/VLVF/VLVFB registers. The logic to determine registers has
been simplified to (vid / 32) and (1 - vid / 32). Many conditional
paths and checks are no longer needed with this patch.

[PATCH v3 23/30] ixgbe/base: add bypassing VLVF

[Beilei Xing]

This patch adds support for the VLVF to be bypassed when adding or
removing a VFTA entry.  The PF can utilize the default pool while
preserving the VLVF for the VFs use.
Meanwhile, update corresponding VF ops and drivers where corresponding
ops is invoked.

[PATCH v3 25/30] ixgbe/base: use u8 to replace u16 for a variable

[Beilei Xing]

Since PCIe standard defines maximum of 8 functions per device lan_id
is a value 0..7. Because of that, lan_id don't need to be u16.

[PATCH v3 27/30] ixgbe/base: allow setting MAC anti spoofing per VF

[Beilei Xing]

Make ixgbe_set_mac_anti_spoofing() consistent with the other
functions that deal with setting VLAN and Ethertype spoofing by
changing the prototype to accept a VF parameter.

Also change the logic for writing the PFVFSPOOF register to be similar
to the MAC and Ethertype functions.

[PATCH v3 28/30] ixgbe/base: add flow control autoneg for X550a

[Beilei Xing]

This patch adds X550a flow control auto negotiation support.
ixgbe_setup_fc_x550a and ixgbe_fc_autoneg_X550a functions where
added to setup and enable flow control. MAC ops function pointer
fc_autoneg was added so that hardware specific fc autoneg functions
can be called from ixgbe_fc_enable_generic.

Yes fixline must be kept on one line.
You can ignore these warnings too.

I think this needs a fuller explanation. Why does the command need a checksum,
and why is the checksum failing? I see in patch 14 makes a similar fix in the
same file, so I think perhaps those two patches should be merged - especially
since patch 14 just claims to fix firmware commands generically.

General comment - please don't start commit messages with "It". There is no
previous noun in the text for the "it" to refer to.

A commit message like this which just restates the commit title can just be
omitted. However, it would be nice to have a little more detail about the
patch in the commit message.

Ideally, this patch should be right after patch 6 - "refactor eee setup for
X550" since that patch does the setup for this one, and refers to it.

NW == "network" or something else? Please expand the acronym.

Also, this commit message is describing what is happening in the changes in the
patch, but it doesn't give any details as to why. Can this message be expanded
to give more details on the reason for change.

[PATCH v4 05/29] ixgbe/base: fix firmware command checksum error

[Beilei Xing]

When software sends commands to firmware using the host
slave command interface, firmware fails to recieve the
request command with a checksum failed error.
This patch sets command checksum to the default value of
0xFF according to datasheet, therefore the checksum won't
be checked by firmware.

Fixes: 86b8fb293fdf ("ixgbe/base: add sw-firmware sync for resource sharing on X550em_a")
Fixes: 0790adeb5675 ("ixgbe/base: support X550em_a device")

[PATCH v4 09/29] ixgbe/base: add link MAC setup for X550a SFP+

[Beilei Xing]

This patch updates ixgbe_setup_mac_link_sfp_x550a for X550 SFP+.
ixgbe_set_lan_id_multi_port_pcie has been updated to set the MAC
instance(0/1) which is needed when configuring the external PHY,
since X550a has two instances of MGPK. The MAC instance is read
from the EEPROM.

[PATCH v4 10/29] ixgbe/base: clear stale pool mappings

[Beilei Xing]

This patch adds clearing the pool mappings when configuring default
MAC addresses for the interface. Without this there will be the risk
of leaking an address into pool 0 which really belongs to VF 0 when
SR-IOV is enabled.

[PATCH v4 16/29] ixgbe/base: change device IDs

[Beilei Xing]

There're two device IDs changed from 15C6/15C7 to 15E4/15E5 cause
PHY info changes. Make the change and use 15C6/15C7 for the backplane
SGMII. Clean up some discovery kludges from the previous shared ID,
and also add 15C6/15C7 to ixgbe_set_mdio_speed just for paranoia
to control MDIO speed even though nothing should be attached.

[PATCH v4 17/29] ixgbe/base: add function to reset swfw semaphore

[Beilei Xing]

For X540 and forward it is possible if a system reset occur at the
right time to leave the SWFW semaphore high. This new function will
attempt to grab and release the semaphore. If the grab times out it
will still release the semaphore placing it in a known good state.
The idea is to call this when you know no one should be holding the
semaphore (i.e. probe time)

[PATCH v4 20/29] ixgbe/base: limit PHY token accessing to MDIO only

[Beilei Xing]

This patch limits getting and putting the PHY Token to PHY MDIO
access only by adding ixgbe_read_phy_reg_x550a and
ixgbe_write_phy_reg_x550a. The PHY Token is only needed to
synchronize access to the MDIO shared between the two MAC instance.

[PATCH v4 21/29] ixgbe/base: simplify add/remove VLANs

[Beilei Xing]

This patch simplifies the adding and removing VLANs from
VFTA/VLVF/VLVFB registers. The logic to determine registers has
been simplified to (vid / 32) and (1 - vid / 32). Many conditional
paths and checks are no longer needed with this patch.

[PATCH v4 22/29] ixgbe/base: add bypassing VLVF

[Beilei Xing]

This patch adds support for the VLVF to be bypassed when adding or
removing a VFTA entry.  The PF can utilize the default pool while
preserving the VLVF for the VFs use.
Meanwhile, update corresponding VF ops and drivers where corresponding
ops is invoked.

[PATCH v4 24/29] ixgbe/base: use u8 to replace u16 for a variable

[Beilei Xing]

Since PCIe standard defines maximum of 8 functions per device lan_id
is a value 0..7. Because of that, lan_id don't need to be u16.

[PATCH v4 26/29] ixgbe/base: allow setting MAC anti spoofing per VF

[Beilei Xing]

Make ixgbe_set_mac_anti_spoofing() consistent with the other
functions that deal with setting VLAN and Ethertype spoofing by
changing the prototype to accept a VF parameter.

Also change the logic for writing the PFVFSPOOF register to be similar
to the MAC and Ethertype functions.

[PATCH v4 27/29] ixgbe/base: add flow control autoneg for X550a

[Beilei Xing]

This patch adds X550a flow control auto negotiation support.
ixgbe_setup_fc_x550a and ixgbe_fc_autoneg_X550a functions where
added to setup and enable flow control. MAC ops function pointer
fc_autoneg was added so that hardware specific fc autoneg functions
can be called from ixgbe_fc_enable_generic.
