I don't see anywhere in this patch or in this series that the
tag_ar9331.c file is being patched to set skb->offload_fwd_mark to true
for packets sent (flooded) to the CPU that have already been forwarded
by the hardware switch. If the software bridge sees a broadcast packet
coming from your driver and it has offload_fwd_mark = false, it will
forward it a second time and the other nodes in your network will see
duplicates.
