  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:

- However, Ubuntu does not see the copper ports... it will only
- address/configure the two SFP+ ports.
+ 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.

+ [TESTING]
+ Boot system, verify four ports are visible and can be addressed and pass data.
