SMAP and newer ps2s

Hi!

I just installed my playstation and noticed I have the "ethernet dies after
brief usage" (with TX problems, still under Linux) problem.

I found an updated smap driver for the linux kernel - is this fixed in
the NetBSD sources already? If not I guess I just volunteered to look
at it, since I can test it easily ;-)
