[issue]
Also media needed to be set to 1000baseT-FDX since auto-negotiate did not
succeed

After boot the primary interface ip address is not pingable, although other
addresses such as default route etc respond normally

tcpdump during ping shows that packets arrive on lo0 with source address
0.0.0.0


[fix]
ifconfig re0 down; ifconfig re0 up

a small script in /usr/local/etc/rc.d/ to implement this seems to deal with the
issue, although it would be good to know why this is happening
