Sorry, but I have sent you several emails telling you about the problems
I have with running the selftests due to changes in the phy etc. Maybe
you have just not received all those emails?

Have you checked spamfilters?

With the kernels now, I cannot even test with the software bridge and
selftests as the compile fails - probably due to changes in uapi headers
compared to what the packages my system uses expects.
