Public bug reported:

Bug discussion and fix upstream from 
http://www.spinics.net/lists/netdev/msg180170.html inter alia.
 
This is a total pain in the arse, as:

* Use laptop on a network which has an ICMP route redirect.
* Suspend laptop
* Restore laptop elsewhere
* Can no longer access internet for 15 minutes, as per discussion on netdev

Not being able to access the internet is a killer, since the network is
the computer.[0]

Please drag this in from upstream as soon as possible, this is a killer.

[0] No, the network is the network, the computer is the computer, sorry
for any confusion.
