ax25: Stop using magic neighbour cache operations.
Before the ax25 stack calls dev_queue_xmit it always calls ax25_type_trans which sets skb->protocol to ETH_P_AX25. Which means that by looking at the protocol type it is possible to detect IP packets that have not been munged by the ax25 stack in ndo_start_xmit and call a function to munge them. Rename ax25_neigh_xmit to ax25_ip_xmit and tweak the return type and value to be appropriate for an ndo_start_xmit function. Update all of the ax25 devices to test the protocol type for ETH_P_IP and return ax25_ip_xmit as the first thing they do. This preserves the existing semantics of IP packet processing, but the timing will be a little different as the IP packets now pass through the qdisc layer before reaching the ax25 ip packet processing. Remove the now unnecessary ax25 neighbour table operations. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
