Subject[PATCH 4.4 06/31] Revert "sit: reload iphdr in ipip6_rcv"
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

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

From: David S. Miller <davem@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.
