The chips vary widely, we experienced great behavioral differences
between steppings.
The 21143 was particulary worrisome, as were some of the 21140
variants. I definitely experienced tx underruns on FreeBSD 3.4 with a
21140A. Never saw them with a good old 21040 though.
After I was told by Intel that they're killing the device off, we
decided to stop developing boards with them and eliminated at least
*that* source of aggravation ;-)
