[SRU][Focal][PATCH 0/2] Intel x710 LOMs do not work on Focal

[Jeff Lane]

[IMPACT]
The Intel x710-TM4 is one of the latest 10GbE controllers from intel using the
i40e driver. This particular 4 port comes in a 2x2 arrangement: 2x SFP+ and 2x
RJ-45. This card is enabled in 5.4 via the inbox version of the i40e driver,
and hwinfo does show both sides of the card but the kernel only sees the two
SFP+ ports and cannot address or use the two copper ports.

These devices have up to 4 ports, but only two seem to work and this has been
seen on at least two different systems using LOMs based on this.

This is currently blocking certification for one of our hardware partners.

[FIX]
This list of Patches enables the latest X710 controller fully:

* 3df5b9a6a9ec i40e: enable X710 support
* d80a476f4a12 i40e: Fix LED blinking flow for X710T*L devices

These are all clean cherry picks from 5.5 into 5.4

My tree with these can be found here:

[TESTCASE]

i40e should load successfully, all ports on Carlsville x710 LOM should be
visible, can be configured, and can pass traffic at full speed.

Test kernels have been verified by the vendor reporting the issue that all
network ports on the LOM are accessible and pass traffic at expected speeds
once the fix is applied.

[REGRESSION RISK]
Should be pretty low. This is a small patch set to a single driver that only
enables a newer chipset.
