ipv4: rate limit updating of next hop exceptions with same pmtu 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. Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: David S.
