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. [FIXES] 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.
