The driver we have here is mostly functional, but we noticed that it was
very prone to causing random kernel lockups, much more so than the tulip
driver.
I also have ported the new driver from 3com (not Donald Becker) to ARM.
The driver has very good performance on receiving data, but transmitting
has problems. I've stopped working on it after I found a few bugs,
because 3com still considers it beta quality.
All of the work on these drivers was done on the 3c905B.
We also did some work on the eepro100 driver a while ago. It worked
pretty well, but that driver had "transmit timeout" problems on both ARM
and x86 platforms. There are rumors that the newest eepro100 driver
fixes this, but I haven't tested it.
Our group doesn't expect to do any more work on these drivers, so if
anyone is interested, let me know.
