This shows that systems sends outgoing LACP multicast ethernet frames just fine,
but NIC chip does not deliver incoming multicast frames (unless switched to promisc. mode).

It may be possible that non-LACP and non-lagg configuration affected too,
like multicast-based protocols OSPF, RIPv2 or even IPv6 that relies on multicast heavily.

SomeOne(TM) with real bxe hardware in hands and code knowledge should commit more tests...
