Subject: xfrm: fix gre key endianess
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=aa285b1740f5b13e5a2606a927f3129954583d78;p=deliverable%2Flinux.git

xfrm: fix gre key endianess

fl->fl_gre_key is network byte order contrary to fl->fl_icmp_*.
Make xfrm_flowi_{s|d}port return network byte order values for gre
key too.
