[RFC PATCH net-next 06/15] ipv4: Handle route deletion notification during flush

[Ido Schimmel]

From: Ido Schimmel <ido...@mellanox.com>

In a similar fashion to previous patch, when a route is deleted as part
of table flushing, promote the next route in the list, if exists.
Otherwise, simply emit a delete notification.
