Subject: ipv6: Don't unset flowi6_proto in ipxip6_tnl_xmit()

From: Eli Cooper <[email protected]>

commit ab34380162cbc9b5172afdadf5136643c687bb73 upstream.

Commit 8eb30be0352d0916 ("ipv6: Create ip6_tnl_xmit") unsets flowi6_proto in ip4ip6_tnl_xmit() and ip6ip6_tnl_xmit(). Since xfrm_selector_match() relies on this info, IPv6 packets sent by an ip6tunnel cannot be properly selected by their protocols after removing it. This patch puts flowi6_proto back.
