	I'm looking into this right now; I'm seeing what I suspect is
the same thing: the ARP traffic for the probes is processed, and the
bonding slaves are marked up, but any other incoming traffic on the VLAN
is dropped.  It might be that just the incoming ARP replies are lost;
I'm not sure yet.  Tcpdump clearly shows the traffic from the peer
arriving.

	This is the patch we put in last week that worked for Andy, but
not for me.  Earlier versions worked fine, so this might be something in
the last version.  With Eric now having issues, perhaps this isn't just
my problem.  Perhaps there's some difference in our configurations that
differs from what Andy has.
