Or are you thinking of trying to cover this with NIPA > HW tests? I have the PHY netdevsim series I can fairly easily rebase, and for port it would be IMO a good idea especially for muxes. Devices with a MII mux are not extremely common, I have a few of'em but having the switchover code in netdevsim would help a lot with the coverage. So I can add netdevsim yeah :) Maxime
