Subject: [PATCH 5.19 0536/1157] ip_tunnels: Add new flow flags field to ip_tunnel_key

From: Paul Chaignon <paul@...valent.com>

[ Upstream commit 451ef36bd229f8aa329cb2258a859b4c636d08ef ]

This commit extends the ip_tunnel_key struct with a new field for the
flow flags, to pass them to the route lookups. This new field will be
populated and used in subsequent commits.
