ipv6: gre: correct calculation of max_headroom
[ Upstream commit 3da812d860755925da890e8c713f2d2e2d7b1bae ]
gre_hlen already accounts for sizeof(struct ipv6_hdr) + gre header,
so initialize max_headroom to zero. Otherwise the
if (encap_limit >= 0) {
max_headroom += 8;
mtu -= 8;
}
increments an uninitialized variable before max_headroom was reset.
