Hi-
I am seeing the following in the ovs-vswitchd.log when sending LLDP 
packets using OpenFlow's Packet Out on OVS 1.2.1:

Sep 07 21:47:08|00151|dpif|WARN|system at xenbr0: execute 1 failed (Invalid 
argument) on packet 00:00:00:00:00:02 > 01:80:c2:00:00:0e, ethertype 
Unknown (0x88cc), length 48:
	0x0000:  0207 0400 0000 0000 0204 0302 0001 0602  ................
	0x0010:  0078 fe0c 0026 e100 0100 0000 0000 0002  .x...&..........
	0x0020:  0000

It appears they are being dropped, as adjacent switches are not 
receiving them.  Interestingly practically the same packets are being 
received by OVS from those same adjacent switches, and sent to the 
controller via Packet In just fine.
