It seems that running tcpdump (and hence enabling promisc mode), causes all multicast packets to dropped with the cpsw driver. We are not using the dual_emac feature, we are just using one port. This is on the DRA7XX.
I see that in dual_emac mode, it is set to ALE_BYPASS (no idea if this works, I haven't tried dual_emac mode). In non dual_emac mode it uses ALE_P0_UNI_FLOOD after flushing the multicast entries. Maybe that's not good enough. -- Len Sorensen -- 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/
