[SK_BUFF]: Introduce skb_reset_network_header(skb)
Arnaldo Carvalho de Melo [Wed, 11 Apr 2007 03:45:18 +0000 (20:45 -0700)]
For the common, open coded 'skb->nh.raw = skb->data' operation, so that we can
later turn skb->nh.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.

This one touches just the most simple case, next will handle the slightly more
"complex" cases.
