New Revision: 205061
URL: http://svn.freebsd.org/changeset/base/205061
Log:
o) Send packets being queued for transmission up to BPF if there's a listener.
o) Properly configure the CAM to handle IFF_PROMISC and note where IFF_ALLMULTI
handling would go if we didn't already force the NIC to receive all
multicast traffic.
