Re: [PATCH] ipv4/fib_trie: notify deleted routes on if down event

This notification is missing in IPv4 (in IPv6, deleted routes are

This is intentional, and your patch has been suggested before.

Routing daemons are expected to purge their tables of all routes for
an interface when the get the interface down event.
