All DSA tag receive functions do strictly the same thing after they have located the originating source port from their tag specific protocol: - push ETH_HLEN bytes - set pkt_type to PACKET_HOST - call eth_type_trans() - bump up counters - call netif_receive_skb() Factor all of that into dsa_switch_rcv(). This also makes us return a pointer to a sk_buff, which makes us symetric with the xmit function. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
