net: cleanup and document skb fclone layout
Lets use a proper structure to clearly document and implement skb fast clones. Then, we might experiment more easily alternative layouts. This patch adds a new skb_fclone_busy() helper, used by tcp and xfrm, to stop leaking of implementation details. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
