ip6_tunnel: Update skb->protocol to ETH_P_IPV6 in ip6_tnl_xmit()
This patch updates skb->protocol to ETH_P_IPV6 in ip6_tnl_xmit() when an IPv6 header is installed to a socket buffer. This is not a cosmetic change. Without updating this value, GSO packets transmitted through an ipip6 tunnel have the protocol of ETH_P_IP and skb_mac_gso_segment() will attempt to call gso_segment() for IPv4, which results in the packets being dropped.
