Related to this, when enabling IFF_PROMISC > in switch mode, all registered multicast addresses are flushed, resulting > in only broadcast and unicast traffic being received. > > A new cpsw_ale_set_allmulti function now scans through the ALE entry > table and adds/removes the host port from the unregistered multicast > port mask of each vlan entry depending on the state of IFF_ALLMULTI. > In promiscious mode, cpsw_ale_set_allmulti is used to force reception > of all multicast traffic in addition to the unicast and broadcast traffic. > > With this change dynamic multicast and promiscious mode both work in > switch mode. > > Signed-off-by: Len Sorensen <lsorense@...lub.uwaterloo.ca> Applied. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
