Connected back to back w/ another box w/ a GigE NIC, it now does 1000baseTX:
igb0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:30:48:c5:db:e2
inet6 fe80::230:48ff:fec5:dbe2%igb0 prefixlen 64 scopeid 0x1
inet 192.168.70.2 netmask 0xffffff00 broadcast 192.168.70.255
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
But still not without problems. I hafta ifconfig down/up it several
times until I can see the other end. W/c is the same for igb1.
