That is, the "status" polling which you disabled?? If so, please update this comment ...

Looks basically OK to me, although I'd rather see the two patches you posted on 27-August be merged into it before an upstream merge. (To use normal MII constants, and handle max size frames.)

He has more experience than I do with respect to these sorts of real Ethernet adapters and usbnet. :)
Speaking of which ... isnt this driver missing a hook to make the MII stuff visible through ethtool?
