Subject: Patch for MTU in the routing table cache

Hi,

after testing the new 3.2 kernel and the new route caching code, i've 
found a bug in net/ipv4/route.c. The route cache does not detect changes 
to the MTU of the interface. Therefore IP fragmentation will happen with 
false MTU. Please see attached the proposed patch.

Best regards,
Simeon Penev
