I haven't done much with PCCARD on -CURRENT lately. Last time I
tried, a couple of months ago, I got repeated freezes on the two 100
Mb/s NICs I have. I've just built a kernel as of about 30 hours ago,
and I find:
1. Xircom RealPort RE-100 (xe driver).
Comes up with unidentified media. Doesn't react to dhclient.
Won't let me set the mediaopt. I have to first set a valid IP
address, after which it comes up as 100baseTX. I can't find a way
to set full-duplex, but maybe the card doesn't support it.
I tried to tar an NFS-mounted file system to see how fast it went:
tar cf /dev/null /src
Almost immediately, I got these messages, repeated frequently:
Jan 13 10:57:29 sydney kernel: xe0: discard oversize frame (ether type 800 flags
3 len 1518 > max 1514)
Jan 13 10:58:13 sydney kernel: xe0: discard oversize frame (ether type 800 flags
3 len 1518 > max 1514)
I checked at the other end and confirmed that the frames were in
fact 1514 bytes long.
2. 3Com 3c905.

Looking at the LEDs on the dongle and on the switch, this card is
in fact in 100baseTX full-duplex mode.
Starting the tar job mentioned before freezes the system within
seconds.
I'm available for testing this if anybody can tell me what to do.
