Subject: ipv4: use tunnel flow flags for tunnel route lookups
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3ae983a603a49e6c80763f747a170b7e987531f3;p=linux.git

ipv4: use tunnel flow flags for tunnel route lookups

Commit 451ef36bd229 ("ip_tunnels: Add new flow flags field to
ip_tunnel_key") added a new field to struct ip_tunnel_key to control
route lookups. Currently the flag is used by vxlan and geneve tunnels;
use it also in udp_tunnel_dst_lookup() so that it affects all tunnel
types relying on this function.
