ok, failure due to the "stmmac: Fix 'eth0: No PHY found' regression"

ok that is expected but the fixed-link will be NOK

thx for having tested it. So it works on real transceiver (tested by
you) and with the fixed-link (tested by me).

ok, I was looking at this problem now that seems to related
the "stmmac: first frame prep at the end of xmit routine"
that, at first glance, is breaking the gmac 3.50 with normal descriptor.
