[PATCH 01/29] net/ixgbe/base: fix check for PHY reset

[Wei Dai]

The previously generic PHY reset check is not sufficient
for the PHY type = ixgbe_phy_x550em_ext_t.
This patch fixes it.

Fixes: af75078fece3 ("first public release")

[PATCH 02/29] net/ixgbe/base: fix condition to clear RAR entry

[Wei Dai]

Specifically the RAR entry for the SAN MAC address is being
cleared when the VMDq pool bits are cleared. In order to prevent
this we need to add an extra check to protect the SAN MAC from
being cleared.

[PATCH 03/29] net/ixgbe/base: use fast MDIO for non-10G MDIO devices

[Wei Dai]

Devices that cannot go 10G can safely select a faster MDIO speed than
those devices that can possibly connect at 10G. So select the higher
speed for those devices.

[PATCH 07/29] net/ixgbe/base: add support to store LED link active

[Wei Dai]

This patch adds support to get the LED link active via the LEDCTL
register. If the LEDCTL register does not have LED link active
(LED mode field = 0x0100) set then default LED link active returned.
LED link active is used for adapter identify/blink support.

[PATCH 08/29] net/ixgbe/base: cleanup logic in X540 checksum calculation

[Wei Dai]

The variable checksum_last_word is used only for a bounds check.
So remove this variable and use IXGBE_EEPROM_CHECKSUM directly.
IXGBE_EEPROM_CHECKSUM value is included in the for loop, but then
it is checked and excluded. Remove the variable checksum_last_word
from the loop so no check is needed.

[PATCH 09/29] net/ixgbe/base: enable LASI interrupts only for X552 devices

[Wei Dai]

Enable the LASI interrupts on X552 devices to receive notifications of the
link configurations of the external PHY and correspondingly support the
configuration of the internal iXFI link, since iXFI does not support
auto-negotiation. This is not required for X553 devices having KR support,
which performs auto-negotiations and which is used as the internal link to
the external PHY. Hence adding a check here to avoid enabling LASI
interrupts for X553 devices. For X553 devices we get link
notifications through LSC interrupts in the MAC. That should suffice to
handle link notifications. The default value of "Link connect/disconnect
mask"  (IXGBE_MDIO_PMA_TX_VEN_LASI_INT_EN) in auto-neg transmit vendor
interrupt mask 2 (7.D401) is 0. Hence added a check that disables code in
ixgbe_x550.c/ixgbe_enable_lasi_ext_t_x550em() that sets this bit and hence
retains the default value for this bit, for X553 devices.

[PATCH 10/29] net/ixgbe/base: add X552 MAC check for iXFI flows

These changes impact the iXFI driver code flow. Since iXFI is only
supported in X552, this patch adds X552 MAC check for iXFI flows.

[PATCH 14/29] net/ixgbe/base: update setup PHY link to unset all speeds

[Wei Dai]

This patch updates ixgbe_setup_phy_link_generic to set/unset
auto-negotiation for all speeds. This ensures that unsupported
speeds are unset. This is necessary since the PHY NVM may
advertise unsupported speeds.

[PATCH 17/29] net/ixgbe/base: support busy SGMII register reads

[Wei Dai]

This patch is needed for base driver support because the NW_MNG_IF_SEL
register fields are used to determine SGMII link for busy SGMII register
reads.

[PATCH 18/29] net/ixgbe/base: include new speeds in VFLINK interpretation

[Wei Dai]

This patch moves some of the extended speeds that come with X552
(5G, 2.5G, 10M) into the link check functions.
 It also now returns speed_unknown for speeds that are not known
how to interpret.

Since only X550 devices have support for 5G, so it should be checked
for that speed on such devices.

[PATCH 20/29] net/ixgbe/base: add physical layer options for FW PHY type

[Wei Dai]

The "FW" PHY type now supports speeds 10M, 100M, and 1G. Previously,
only the 1G speed was reported in the
ixgbe_get_supported_physical_layer_X550em() function for this PHY type.
This patch is to add the 10M and 100M options.

[PATCH 22/29] net/ixgbe/base: remove unused PHY ID

[Wei Dai]

The first PHY ID for X550 was only used on original HW and
never released. So remove these unused PHY ID.

[PATCH 23/29] net/ixgbe/base: update FW PHY flow control

[Wei Dai]

This patch removes the flow control conversion from rx and tx to pause and
asymmetric pause, as that is handled by the call to ixgbe_negotiate_fc.
Performing the conversion prior to calling ixgbe_negotiate_fc results in
an incorrect fc mode if RX only pause is selected when the link partner is
advertising TX.

[PATCH 24/29] net/ixgbe/base: add EEE support for DNL-controlled PHYs

[Wei Dai]

This patch adds EEE support for DNL-controlled PHYs. Because DNL
does not indicate EEE capability or status, this patch simply
assumes that it is supported. As soon as there is a DNL-supported
PHY that does not support EEE, there will be defects in this area
because the driver will not report the EEE status correctly.
This also deletes some now-unused definitions from an earlier
Marvell PHY implementation and combines a device ID check into a
switch statement.

[PATCH 27/29] net/ixgbe/base: add write flush required by Inphi

[Wei Dai]

This patch updates Inphi configuration to flush the register write with
a reg read. Inphi is configured in ixgbe_setup_mac_link_sfp_x550a.
The Inphy setup flow has been updated to read configuration reg, write
only linear/non-linear, and then read (write flush).

This seems not related to this patchset, also patch 15/29 has [1] again
seems unrelated to that patch, does it make sense to make these a
separate patch?

I guess version needs to be updated to 2016.11.21 ?

DNL is short for name of some method to control Marvel PHY.
This git log message will be revised in v2 patch set.

Yes, in v2 patch set, removing of above enum type will be in a separate one.

Inphi (www.inphi.com) is a company which provides PHYs.
So I will use "Inphi PHY" instead of "Inphi" in v2 patch set.

Yes, following statement is redundant, but in order to simplify the process to 
keep up with the shared code provided by another team (Intel Network Division), 
I'd like to keep it here. Anyway it is harmless.

It will be corrected in v2 patch.
