This is a good point that bears highlighting. Donald Becker's [and thus the kernel's] eepro100.c had certain bugs for years, simply because access to Intel E100 hardware docs was damn near impossible to obtain. I don't see driver hardening being very feasible on such drivers, where the vendor refuses to allow kernel engineers access needed to get their hardware working and stable. [why vendors want crappy Linux support, I'll never know] Jeff P.S. In all fairness, Intel is doing a really good job maintaining the e100 and e1000 drivers nowadays, and e100 docs should be public very soon.
