ipv4: Handle route deletion notification during flush

idosch · davem330 · commit 525bc345fcbc · 2019-12-16T16:14:42.000-08:00
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.
