net: Copy inner L3 and L4 headers as unaligned on GRE TEB

Browse source

[ Upstream commit 78565208d7 ]

This patch corrects the unaligned accesses seen on GRE TEB tunnels when
generating hash keys.  Specifically what this patch does is make it so that
we force the use of skb_copy_bits when the GRE inner headers will be
unaligned due to NET_IP_ALIGNED being a non-zero value.
