sk_buff: drop all skb extensions on free and skb scrubbing
Now that we have a 3rd extension, add a new helper that drops the extension space and use it when we need to scrub an sk_buff. At this time, scrubbing clears secpath and bridge netfilter data, but retains the tc skb extension, after this patch all three get cleared. NAPI reuse/free assumes we can only have a secpath attached to skb, but it seems better to clear all extensions there as well. v2: add unlikely hint (Eric Dumazet) Fixes: 95a7233c452a ("net: openvswitch: Set OvS recirc_id from tc chain index") Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S.
