net: add skb frag size accessors
Eric Dumazet [Tue, 18 Oct 2011 21:00:24 +0000 (21:00 +0000)]
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.
