I have an Intel E810 card (supported by the "ice" driver). I have the 4 port, 25gbps version.
The ice driver does not support changing speed, duplex, or autonegotiation settings (I have no idea why, but it doesn't). I pasted the driver README on this at the end of the report. I am running VYOS in libvirt, and am handing it VF's (so vyos is using iavf rather than ice) but it inherits the same limitation. If i pass through the physical port so vyos uses the ice driver directly, it has the same issue (plus it does not set up the DDP).
VYOS appears to append speed=auto, duplex=auto to configs before processing them with ifconfig/ethernet.py. As a result, it tries to change the autonegotiation state on the card when i run commit, and when it fails, you can't save. This is noted in the docs as a default, so not surprising.
If i modify config.boot directly, it works fine.
The inability to change speed/duplex appears to have happened before :). If i add iavf to the list of drivers in ethtool.py not support speed, auto, all works correctly.
iavf only supports cards that use the i40e and ice drivers. The i40e driver has the same limitation of not setting speed/duplex and same note in the readme file. So i will add i40e (and ice) to the list as well. I have tested ice, but i can't test i40e easily.
For completeness I've pasted a log showing what happens. The printout you see before "VYOS had an issue completing a command" is me adding print(config) right before the speed/duplex processing in ethernet.py when i was trying to figure out what was going on.

Speed and Duplex Configuration ------------------------------ You cannot set speed, duplex, or autonegotiation settings using ethtool. To see the speed configurations your device supports, run the following: # ethtool <ethX> To have your device advertise supported speeds, use the following: # ethtool -s <ethX> advertise N Where N is a bitmask of the desired speeds. For example, to have your device advertise 10000baseSR Full, use: # ethtool -s <ethX> advertise 0x80000000000 For more details, please refer to the ethtool man page.
