From 5b8fcc075714b86fb8fe194bb463fed2998a8e85 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 6 Jun 2017 11:34:06 -0400 Subject: [PATCH] Revert "sit: reload iphdr in ipip6_rcv" 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. Signed-off-by: David S.
