Subject: [PATCH net-next 4/7] ipv4: use tunnel flow flags for tunnel route lookups
Date:   Mon,  9 Oct 2023 10:20:56 +0200

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.
