This fixes the same nasty problem on my AR2425.
My AR2425 will stall if it transmits for about 1~2 minutes.
It sends storm of RXORN interrupts although it only transmits.
I see that now lspci calls it AR5001.
Jussi Kivilinna, million thanks to you. I would never think of going
this direction.
Luis, so I was right after all, wasn't I?
It is a hardware bug that is worked around in windows driver by
disabling PCIE ASPM L0S.
Jussi Kivilinna, thanks again, I really mean it.
Best regards,
Maxim Levitsky
