Subject: ipv6: gre: fix wrong skb->protocol in WCCP
From: Yuri Chislov <yuri.chislov@xxxxxxxxx>
[ Upstream commit be6572fdb1bfbe23b2624d477de50af50b02f5d6 ]
When using GRE redirection in WCCP, it sets the wrong skb->protocol,
that is, ETH_P_IP instead of ETH_P_IPV6 for the encapuslated traffic.
Fixes: c12b395a4664 ("gre: Support GRE over IPv6")
