From 9e903e085262ffbf1fc44a17ac06058aca03524a Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 18 Oct 2011 21:00:24 +0000 Subject: net: add skb frag size accessors To ease skb->truesize sanitization, its better to be able to localize all references to skb frags size. Define accessors : skb_frag_size() to fetch frag size, and skb_frag_size_{set|add|sub}() to manipulate it. Signed-off-by: Eric Dumazet Signed-off-by: David S.
