net: Start with correct mac_len in skb_network_protocol
Sometimes, when the packet arrives at skb_mac_gso_segment() its skb->mac_len already accounts for some of the mac lenght headers in the packet. This seems to happen when forwarding through and OpenSSL tunnel. When we start looking for any vlan headers in skb_network_protocol() we seem to ignore any of the already known mac headers and start with an ETH_HLEN. This results in an incorrect offset, dropped TSO frames and general slowness of the connection. We can start counting from the known skb->mac_len and return at least that much if all mac level headers are known and accounted for.
