Title:
[Regression] 5.4 is not identifying all ports on Intel x710-TM4 10GbE
controller
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Focal:
Confirmed
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.
This is currently blocking certification for one of our hardware
partners.
After some investigation we see this works in a more recent version of
the driver. Intel suggests the commit in FIXES from 5.5 should make
this work.
This is a regression from the i40e driver in Bionic (5.3 HWE) that,
per the tester, does show all four ports.

3df5b9a6a9ec3c1e4431bf1db3426b54dc92dd91 i40e: enable X710 support
I have a branch here:
https://code.launchpad.net/~bladernr/ubuntu/+source/linux/+git/focal/+ref/1887703-i40e-enable-x710
[TESTING]
Boot system, verify four ports are visible and can be addressed and pass data.
