I could reproduce where an interface configured with type p2p in
ospf6d.conf reverts back to BROADCAST after a link bounce.
When an interface receives a link update (RTM_IFINFO), if_update()
unconditionally re-derives iface->type from interface flags
(IFF_POINTOPOINT, IFF_BROADCAST), overwriting the explicit configuration
set during parsing.
Diff below introduces F_IFACE_TYPE in cflags to track when an interface
type was set by configuration, and only auto-derive the type from
interface flags when F_IFACE_TYPE is not set.
I am far from an expert here, so any feedback is appreciated.
