em(4) not sending/receiving data in recent current ?

Hi all,

I recently upgraded a system (Dell Vostro desktop) running
8.0-CURRENT/amd64 from July to -current from a few days ago,
and em(4) stopped working.

By this I mean:

- em0 probes and attaches correctly
- link is detected
- sending any data to/from the host simply fails

tcpdump shows incoming ARP requests and they seem to be accepted
by the ARP stack, and pinging another host shows outgoing ARP requests, but
nothing is seen on the wire by the other hosts.

Anyone else experiencing this, and could this be related to the
em/e1000/igb split ?

Cheers,
Phil
