When a link's carrier goes down it could be a sign of the port changing networks. If the new network has overlapping addresses with the old one, then the kernel will continue trying to use neighbor entries established based on the old network until the entries finally age out - meaning a potentially long delay with communications not working. This patch evicts neighbor entries on carrier down with the exception of those marked permanent. Permanent entries are managed by userspace (either an admin or a routing daemon such as FRR).
