Deleting lport when multicast mod is configured to
FM10K_XCAST_MODE_ALLMULTI or FM10K_XCAST_MODE_PROMISC will
result in generating orphaned multicast-group entries in the
switch manager.
Before deleting the lport, reset multicast mode to
FM10K_XCAST_MODE_NONE to flush out these multicast-group
entries.

Some defines were previously wrapped to strip them from opensource driver
builds, but these are required by DPDK. Change the wrapping of these so
that the DPDK gets them as long as DPDK_SUPPORT is correctly added as a
strip flag, while we can remove the reduandant ones in fm10k_osdep.h.

Clean up the logic in fm10k_tlv_attr_parse, we
should not reply on that FM10K_NOT_IMPLEMENTED is
greater than zero, as this can easily cause confusion.
The patch also correct a minor document error.

The diagram represents bit layout of the multi-bit VLAN update
message format. Re-draw the numbers using base 8, and mark the
bit values every 8 bits at the top. This should make it more
easy to grasp the table quickly.

Use a new #define FM10K_VLAN_OVERRIDE even though we're using
the exact same bit. The reason for this is clarity in the code,
otherwise you can read FM10K_VLAN_CLEAR and think it should be
removed. Also add a comment explaining why the FM10K_VLAN_OVERRIDE
bit is set.

The original comment may be read incorrectly as referring to checking
the *entire* length is zero. However, it merely checks only the reserved
bits of both length and reserved in a small amount of code. Update the
comment to indicate this is a clever trick and clearly spell out that it
only checks the reserve bits.

The VF uses a multi-bit update request to clear unused VLANs whenever it
resets. However, an accident in a previous refector broke multi-bit
updates for VFs, due to misreading a comment in fm10k_vf.c and
attempting to reduce code duplication. The problem occurs because
a multi-bit request has a non-zero length, and the PF would simply drop
any request with the upper 16 bits set. In addition, a multi-bit vlan
update does not have a concept for "VLAN 0" as the single bit update
does.
A previous revision of this patch resolved the issue by simply removing
the upper 16 bit check and the iov_select_vid checks. However, this would
remove the checks for default VID and for ensuring no other VLANs can be
enabled except pf_vid when it has been set. To resolve that issue, this
revision uses the iov_select_vid when we have a single-bit update, and
denies any multi-bit update when the VLAN was administratively set by
the PF. This should be ok since the PF properly updates VLAN_TABLE when
it assigns the PF vid. This ensures that requests to add or "remove" the
PF vid work as expected, but a rogue VF could not use the multi-bit
update as a loophole to attempt receiving traffic on other VLANs.

If the fm10k interface is brought up, but the switch manager software is
not running, the driver will continuously request the lport map every
few seconds in the base driver watchdog routine. Eventually after
several minutes the switch mailbox Tx fifo will fill up and the mailbox
will timeout, resulting in a reset. This reset will appear as if for no
reason, and occurs regularly every few minutes until the switch manager
software is loaded.

Don't report FM10K_ERR_REQUESTS_PENDING when we fail to disable queues
within the timeout. This can occur due to a hardware Tx hang, or when
the switch ethernet fabric is resetting while we are transmitting
traffic. It can sometimes take up to 500ms before the Tx DMA engine
gives up. Instead, just skip the DMA engine check and perform
a data-path reset anyways. Add a statistic counter to keep track of the
number of resets occurring while we have pending DMA on the rings.
In order to prevent having to assign err = FM10K_SUCCESS, re-order the
last few items of the reset_hw_pf function so that we don't perform
"return err" at the end.

Avoid potential FUM fault errors on a VF when updating MAC address
and VLAN information. Only use the register flow when the mailbox is
disconnected, by checking if the enqueue_tx returns
FM10K_MBX_ERR_NO_MBX. If the mailbox message can be sent, there is no
reason to bother with the register writes which are only intended to
be used during VF driver initialization.

Other shared code bases are planning on using
IS_MULTICAST_ETHER_ADDR and friends without leaving the driver
name in the macro.
Remove reference to FM10K here so that we can re-use the specific
compat flags from Linux.

Multiple IES API resets can cause a race condition where the mailbox
interrupt request bits can be cleared before being handled. This can
leave certain mailbox messages from the PF to be untreated and the PF
will enter in some inactive state. If this situation occurs, the IES API
will initiate a mailbox version reset which, then, trigger a mailbox
state change. Once this mailbox transition occurs (from OPEN to CONNECT
state), a request for reset will be returned.

Hi Qi,
Is there a base code version to record for fm10k, as done in some other
drivers?

If that is the case, these #ifdefs should not be released code, they
should be stripped but only #defines should remain, is this correct?

Deleting lport when multicast mod is configured to
FM10K_XCAST_MODE_ALLMULTI or FM10K_XCAST_MODE_PROMISC will
result in generating orphaned multicast-group entries in the
switch manager.
Before deleting the lport, reset multicast mode to
FM10K_XCAST_MODE_NONE to flush out these multicast-group
entries.

Clean up the logic in fm10k_tlv_attr_parse, we
should not reply on that FM10K_NOT_IMPLEMENTED is
greater than zero, as this can easily cause confusion.
The patch also correct a minor document error.

Add FM10K_PF_ATTR_ID_ERR, since it is possible for the switch manager
to send out an error message indicating status of the LPORT_MAP due to
zero allocated bandwidth.

The diagram represents bit layout of the multi-bit VLAN update
message format. Re-draw the numbers using base 8, and mark the
bit values every 8 bits at the top. This should make it more
easy to grasp the table quickly.

Use a new #define FM10K_VLAN_OVERRIDE even though we're using
the exact same bit. The reason for this is clarity in the code,
otherwise you can read FM10K_VLAN_CLEAR and think it should be
removed. Also add a comment explaining why the FM10K_VLAN_OVERRIDE
bit is set.

The original comment may be read incorrectly as referring to checking
the *entire* length is zero. However, it merely checks only the reserved
bits of both length and reserved in a small amount of code. Update the
comment to indicate this is a clever trick and clearly spell out that it
only checks the reserve bits.

The VF uses a multi-bit update request to clear unused VLANs whenever it
resets. However, an accident in a previous refactor broke multi-bit
updates for VFs, due to misreading a comment in fm10k_vf.c and
attempting to reduce code duplication. The problem occurs because
a multi-bit request has a non-zero length, and the PF would simply drop
any request with the upper 16 bits set. In addition, a multi-bit vlan
update does not have a concept for "VLAN 0" as the single bit update
does.
A previous revision of this patch resolved the issue by simply removing
the upper 16 bit check and the iov_select_vid checks. However, this would
remove the checks for default VID and for ensuring no other VLANs can be
enabled except pf_vid when it has been set. To resolve that issue, this
revision uses the iov_select_vid when we have a single-bit update, and
denies any multi-bit update when the VLAN was administratively set by
the PF. This should be ok since the PF properly updates VLAN_TABLE when
it assigns the PF vid. This ensures that requests to add or "remove" the
PF vid work as expected, but a rogue VF could not use the multi-bit
update as a loophole to attempt receiving traffic on other VLANs.

If the fm10k interface is brought up, but the switch manager software is
not running, the driver will continuously request the lport map every
few seconds in the base driver watchdog routine. Eventually after
several minutes the switch mailbox Tx fifo will fill up and the mailbox
will timeout, resulting in a reset. This reset will appear as if for no
reason, and occurs regularly every few minutes until the switch manager
software is loaded.

Don't report FM10K_ERR_REQUESTS_PENDING when we fail to disable queues
within the timeout. This can occur due to a hardware Tx hang, or when
the switch ethernet fabric is resetting while we are transmitting
traffic. It can sometimes take up to 500ms before the Tx DMA engine
gives up. Instead, just skip the DMA engine check and perform
a data-path reset anyways. Add a statistic counter to keep track of the
number of resets occurring while we have pending DMA on the rings.
In order to prevent having to assign err = FM10K_SUCCESS, re-order the
last few items of the reset_hw_pf function so that we don't perform
"return err" at the end.

Avoid potential FUM fault errors on a VF when updating MAC address
and VLAN information. Only use the register flow when the mailbox is
disconnected, by checking if the enqueue_tx returns
FM10K_MBX_ERR_NO_MBX. If the mailbox message can be sent, there is no
reason to bother with the register writes which are only intended to
be used during VF driver initialization.

Other shared code bases are planning on using
IS_MULTICAST_ETHER_ADDR and friends without leaving the driver
name in the macro.
Remove reference to FM10K here so that we can re-use the specific
compat flags from Linux.

Multiple IES API resets can cause a race condition where the mailbox
interrupt request bits can be cleared before being handled. This can
leave certain mailbox messages from the PF to be untreated and the PF
will enter in some inactive state. If this situation occurs, the IES API
will initiate a mailbox version reset which, then, trigger a mailbox
state change. Once this mailbox transition occurs (from OPEN to CONNECT
state), a request for reset will be returned.

Series applied to dpdk-next-net/master, thanks.
defined(DPDK_SUPPORT) removed from patch 3/18, which is useless and
looks like exists by mistake, please double check updated code.
