Thanks Ben. Sorry, i meant frames are getting discarded, not the flows. I
think i get the reason. It's probably because the normal flow and the
flow i installed are of equal priority (0) which may be why it's
probably picking the normal flow whose action is to drop the frame with
reserved DMAC. Now, when i install the flow for LLDP frame, i specify a
priority of 99 and that seems to work.
I have sent the Patch to the dev mailing list along with the description. The
change is basically:
