> The cpsw driver did not support the IFF_ALLMULTI flag which makes dynamic > multicast routing rather hard to handle. Related to this, when enabling > IFF_PROMISC in non dual_emac mode, all registered vlans are flushed, > and only broadcast and unicast are allowed which isn't what you would > want from IFF_PROMISC. > > A new cpsw_ale_set_allmulti function now scans through the ALE entry > table and adds or removes the host port from the unregistered multicast > port mask depending on the state of IFF_ALLMULTI. In promisc mode, > it is also called to enable reception of all multicast traffic. > > With this change I am now able to run dynamic multicast routing and also > use tcpdump and actually see multicast traffic. > > Signed-off-by: Len Sorensen <[email protected]> Please fix your Subject line and resubmit this patch. Subject lines end up as the commit message header text, and therefore must be of the form: subsystem: Description. In this case "cpsw: " is probably an appropriate subsystem prefix. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
