I'm a bit puzzled by that.  I don't have the bridge module (or brcompat)
in my module stack.  So, I'm curious where those LLDP multicasts are 
being dropped.  

Two other datapoints 

1) I connected my switch to Windows7 machine running wireshark and it 
   does not see the discovery packets using *either*  address.

2) When I monitor /proc/net/dev on the openwrt switch, the transmitted packet
   count increases by 1 about every 5 seconds.   So, I think the packets
   are really being sent.  However, on the linux machine running wireshark
   the received packet count on the interface is not incremented.  The only
   thing between the switch and the PC is a wire, so either the packets
   are not actually going out on the wire (even though the switch thinks
   so), or they are getting dropped at a very low level in the linux
   networking stack.

Has anyone else observed a problem with LLDP packets being "invisible"
to wireshark?
