This is a patched bridge module for linux kernel linux-2.6.18-348.18.1.el5.
This module have disabled check for link-local multicast frames such as LACP or any other multicast frames in the range 01:80:C2:00:0x.
I have used it for special test case.
br_input.c:
/* the check is disabled for LACP over bridge testing purposes
if (unlikely(is_link_local(dest))) {
skb->pkt_type = PACKET_HOST;
return NF_HOOK(PF_BRIDGE, NF_BR_LOCAL_IN, skb, skb->dev,
NULL, br_handle_local_finish) != 0;
}
