-Subject: [PATCH 4/6] ipv4: rate limit updating of next hop exceptions with
- same pmtu
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The tunnel devices call update_pmtu for each packet sent, this causes
-contention on the fnhe_lock. Ignore the pmtu update if pmtu is not
-actually changed, and there is still plenty of time before the entry
-expires.
