Title:
Intel x710 LOMs do not work on Focal
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Focal:
Fix Committed
Bug description:
[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, configurable, 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.
[REGRESSION RISK]
Possible problem could be if the LED patch causes LEDs to not function
correctly (or not at all) but the risk for this is pretty low.
