I tried my 3C905 (not 3C905B) with new xl driver. It works almost
well, but the auto negotiation (under 10M and half-duplex) invoked by
'ifconfig xl0 media autoselect' sometimes fails.

xl1: autoneg not complete, no carrier
After setting 'ifconfig xl0 media 10BaseT/UTP' I tried the auto
negotiation again, and it returns a successful message.
xl1: selecting MII, 10Mbps, half duplex
xl1: autoneg complete, link status good (half-duplex, 10Mbps)
But, alas, the network is still dead. I have to explicitly specify the
media to enable the network. I am going to look into this problem.
By the way, here is my patch for its multicast support, which is not
tested yet.
