#1421169 — [PATCH 3.16 082/114] macvtap: segmented packet is consumed

3.16.36-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <edumazet@google.com>

commit be0bd3160165e42783d8215f426e41c07179c08a upstream.

If GSO packet is segmented and its segments are properly queued,
we call consume_skb() instead of kfree_skb() to be drop monitor
friendly.

Fixes: 3e4f8b7873709 ("macvtap: Perform GSO on forwarding path.")
