It is a vicious cir= cle as ethtool need this to be merge before supporting it. Would it be ok to accept it like that and wait for ethtool support to add t= he selftest? Otherwise I could test it through ynl python command but there is no similar cases in the selftest. Nevertheless, it would have been nicer to point this out earlier in the ser= ies.
