You definitely need the patch that reverts readq and writeq back to use
two 32bit accesses for the ASMedia controller to work at all.
I'm also seeing a lot of 'odd' messages when the ax88179 card in plugged in
(and it sometimes gets picked up at 480M).
I'm not looking into those.
But there are also further issues I'm about to look at.
Short 'ping' requests work, but a 'netperf' tcp rr test with 8k blocks
(which probably generates sg transmits) fails generating some
'TRB DMA ptr not part of current TD' errors.
I think I've seem that when a 'TRB error' is reported (when I was using the
wrong type of NOP). I'm about to investigate what is being errored here.

Dunno ...
