parent[IPSEC]: Set skb->data to payload in x->mode->output (diff)
[IPSEC]: Use IPv6 calling convention as the convention for x->mode->output
The IPv6 calling convention for x->mode->output is more general and could help an eventual protocol-generic x->type->output implementation. This patch adopts it for IPv4 as well and modifies the IPv4 type output functions accordingly. It also rewrites the IPv6 mac/transport header calculation to be based off the network header where practical. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
