ip6_gre: Make o_seqno start from 0 in native mode
[ Upstream commit fde98ae91f79cab4e020f40c35ed23cbdc59661c ]
For IP6GRE and IP6GRETAP devices, currently o_seqno starts from 1 in
native mode. According to RFC 2890 2.2., "The first datagram is sent
with a sequence number of 0." Fix it.
It is worth mentioning that o_seqno already starts from 0 in collect_md
mode, see the "if (tunnel->parms.collect_md)" clause in __gre6_xmit(),
where tunnel->o_seqno is passed to gre_build_header() before getting
incremented.
Fixes: c12b395a4664 ("gre: Support GRE over IPv6")
