im no bsd driver expert, for sure... experts please
step forward... can you dump out
sc->sk_vpd_readonly?
i did and it returns (in part) PN40-0779-000ERev 1.2MN
3ComSN
40-0779-000 is the 'id' for the 3c940, ref site:
http://www.idhw.com/textual/chip/3com/chippicture.html
it would be interesting to see what the k8vse readonly
vpd returns. the linux driver seems to read the enire
vpd, and parse it for the name, vendor id, readonly,
r/w, etc. parts of the vpd. so i would agree that
using 0x3f (for example) in freebsd isnt the same as
in linux
