ip_gre: Make o_seqno start from 0 in native mode
[ Upstream commit ff827beb706ed719c766acf36449801ded0c17fc ]
For GRE and GRETAP 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 gre_fb_xmit(), where tunnel->o_seqno is passed to
gre_build_header() before getting incremented.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
