From c1d2bbe1cd6c7bbdc6d532cefebb66c7efb789ce Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 10 Apr 2007 20:45:18 -0700 Subject: [SK_BUFF]: Introduce skb_reset_network_header(skb) 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. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S.
