Further update, According to the engineer at SMC, they did try "18.04.3" (not sure if that means 4.15, or 5.3, hopefully not 5.2) and all four ports did work for them, so this appears to be a regression in the i40e driver.
I've asked him to provide more info about what kernels they have tried specifically to help narrow down where it breaks. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1887703 Title: 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: The Intel x710-TM4 is one of the latest 10GbE controllers from intel using the i40e driver.
