Title:
  ICMP redirect routes cached forever

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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.
