AX8817x (USB ethernet) problem in 2.6.0-test1

[Måns Rullgård]

My Netgear FA120 USB2 ethernet adaptor isn't working properly with
Linux 2.6.0-test1.  First off, I had to modify it slightly (patch
below) to make it work at all with USB2.  Now I can send data at the
full expected speed (~11 MB/s).  The problem is that receiving is only
200 kb/s.  This is obviously annoying.  For the record, it works
perfectly with 2.4.21-pre5 and ax8817x.c version 0.9.7.  Any ideas?

Has anyone looked into what might be causing the terrible receive
performance I'm seeing?  The module author, Dave Hollis, had some
ideas, but I don't know where he's been lately.  Are you there, Dave?

Are there more values with different meanings for USB2 devices?
