ip_local_out missing skb->protocol assignment

Hi,


I noticed that skb->protocol is not set for Netfilter hooks with 
NF_INET_LOCAL_OUT. Reason for that is that skb->protocol is only set 
within ip_output, i.e. shortly before NF_INET_POST_ROUTING. Was there a 
specific reason setting ->protocol is delayed for locally-output 
traffic?
