3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <eric.duma...@gmail.com>
commit 2ad5b9e4bd314fc685086b99e90e5de3bc59e26b upstream.
Torsten Luettgert bisected TEE regression starting with commit
f8126f1d5136be1 (ipv4: Adjust semantics of rt->rt_gateway.)
The problem is that it tries to ARP-lookup the original destination
address of the forwarded packet, not the address of the gateway.
Fix this using FLOWI_FLAG_KNOWN_NH Julian added in commit
c92b96553a80c1 (ipv4: Add FLOWI_FLAG_KNOWN_NH), so that known
nexthop (info->gw.ip) has preference on resolving.
