[avahi] Can;t get avahi to announce anything

I've been doing some debugging on this today and traced through the code
in gdb and it looks like it is making it all the way to the sendmsg()
call and that is succeeding, but nothing still makes it out the wire.
Pokign around inside gdb, the src and dest addresses on the packets it
is trying to send out look ok to me (src is the ip address on the
interface and dst is the mDNS mcast group -- 224.0.0.251). Any idea on
how to debug what is happening once the sendmsg system call is made? I
would assume sendmsg would get a failure code if there was something
wrong with the packet it got sent and it didn't know where to send it,
etc.? I even took wireshark and looked at the physical ethernet
interface just to make sure it wasn't get sent out on the physical
interface untagged and the packets didn't show up at all (either vlan
tagged or not).
Since none of the previous versions work for me, its possible that this
has something to do with my vlan setup, but i'm not not quite sure where
to look from here.
Thanks.
