4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: David S. Miller <da...@davemloft.net>
commit f4eb17e1efe538d4da7d574bedb00a8dafcc26b7 upstream.
This reverts commit b699d0035836f6712917a41e7ae58d84359b8ff9.
As per Eric Dumazet, the pskb_may_pull() is a NOP in this
particular case, so the 'iph' reload is unnecessary.
