rps: Add flag to skb to indicate rxhash is based on L4 tuple
The l4_rxhash flag was added to the skb structure to indicate that the rxhash value was computed over the 4 tuple for the packet which includes the port information in the encapsulated transport packet. This is used by the stack to preserve the rxhash value in __skb_rx_tunnel. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
