Hi everyone;
Using freeBsd 5.3.
Trying to get the gigabit sk driver to work but even if I force it to 100baseTX
full-duplex I still
get when doing an ftp session:
sk0: discard oversize frame (ether type ....)
sk0: discard frame w/o leading ethernet header ( len 0 pkt len 0)
The transfer finishes ok though.
I have two machines conected via crossover cat 5 RJ-45. Besides the above
errors, I get a 3.5 MB/s
tranfer rate, which is way bellow the 10 MB/s I get when doing the same thing
with 2 via-rhine
boards.
I found this patch on google, but it�s a bit outside of my programming skills:

============================================
The person who found it said that he grabbed from netbsd.
Maybe one of you guys can shed some light on this for me.
Thanks,
