Comment 1 for bug 58927

Confirm this problem with Edgy knot3 upgraded from Dapper. Can't get an IP for eth0, message is same as "send_packet: Message too long".

$lspci | grep Ethernet
00:12.0 Ethernet controller: National Semiconductor Corporation DP83815 (MacPhyter) Ethernet Controller

$lsmod | grep nat*
natsemi 30112 0

And, "sudo dhclient wlan0" (zd1211) is OK to get an IP, however there is "SIOCSIFMTU: Invalid argument" message.
