Hi!
After some more work on the driver, it's bugfree(tm) now, possibly
except for a couple harmless race conditions and some stuff in the
multicast filters, which I wasn't able to test much. It does about
600-700 KB/sec on UHCI, haven't measured it on OHCI yet.
It should work with the following USB devices:
Belkin F5U111
CATC Netmate
CATC Netmate II
smartBridges smartNIC
The patch is agains 2.4.5-ac12, but should patch cleanly against almost
any other recent kernel.
Johannes: Although marked EXPERIMENTAL, because I was the only one to
test it, it should be pretty stable. Please send it to Alan/Linus for
inclusion in the kernel.
