Subject: macvtap: segmented packet is consumed
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.")
