There are only two implementaions, one for ipv4 and one for ipv6. Both are almost identical, they clear skb->cb[], set the TRANSFORMED flag in IP(6)CB and then call the common xfrm_output() function. By placing the IPCB handling into the common function, we avoid the need for the output_finish indirection as the output functions can simply use xfrm_output().
