The interface didn't automatically become useful on reboot. This time
I had to log in via console and do the ifconfig ue0 down up dance then
wait about 30 seconds.

freebsd@generic:~ $ ifconfig ue0
ue0: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> 
      metric 0 mtu 1500
      options=8000b<RXCSUM,TXCSUM,VLAN_MTU,LINKSTATE>

      inet 192.168.1.129 netmask 0xffffff00 broadcast 192.168.1.255
      media: Ethernet autoselect (1000baseT <full-duplex>) status: active
      nd6 options=829<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL,STABLEADDR>

freebsd@generic:~ $ iperf3 -c 192.168.1.230 --time 60 --get-server-output

Paging the interface down/up again didnt increase throughput.
# ifconfig ue0 lro tso -rxcsum -txcsum

weird how it jumps from ~180 to ~480 and when it's at ~480 it's erroring.

I'll remove the 'if_axge_load="YES"' from /etc/loader.conf and compile 
it into the kernel as per the manpage and re-test.
