Hi folks...

Well, at least the newer 3Com 10/100 cards (the Ethernet/Modem combo cards)
should work now, thanks to PR #8331 from Ryoji KATO.

It also makes the 3c574 that was loaned to me that much closer to working:

pcmcia1 at pcic0 controller 0 socket 1
ep0 at pcmcia1 function 0 port 0x340-0x35f: 3Com 3c574-TX 10/100Mbps Ethernet
ep0: address 00:60:08:b3:ce:f4, 64KB word-wide FIFO, 1:1 Rx:Tx split
tqphy0 at ep0 phy 0: 78Q2120 10/100 media interface, rev. 3
tqphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

This worked long enough for my laptop to obtain an address from the DHCP
server (the 10Mb/s light lit up properly and everything), but then the
link light goes out, the PHY reports "none" as the current media, and
packets no longer hit the wire (though the MAC seems to think everything
is still okay).

sys/dev/mii/tqphyreg.h has a note in it regarding hardware bugs that exist
on <= rev 3 of the 78Q2120.  I'll so some more investigating to see what I
can find out.
