Subject: [PATCH net v4 0/4] vrf: fix source address selection with route leak

For patch 1 and 2, I didn't find the exact commit that introduced this bug, but
I suspect it has been here since the first version. I arbitrarily choose one.

v3 -> v4:
 patch 2: set 'dev' only when needed

v2 -> v3:
 patch 1: enforce 80 columns limit
 patch 2: fix coding style
 patch 4: add tcp and udp tests

v1 -> v2:
 patch 2: Fix 'same_vrf' calculation in patch
 patch 4: remove test about the topology type (only symmetric topology is
          supported now).
