Merge branch 'l3mdev_saddr_op'

David Ahern says:

====================
net: Add saddr op to l3mdev and vrf

First 2 patches are re-sends of patches that got lost in the ethosphere
Tuesday; they were part of the first round of l3mdev conversions.
Next 3 handle the source address lookup for raw and datagram sockets
bound to a VRF device.

The conversion to the get_saddr op also fixes locally originated TCP
packets showing up at the VRF device. The use of the FLOWI_FLAG_L3MDEV_SRC
flag in ip_route_connect_init was causing locally generated packets
to skip the VRF device.

v2
- rebased to top of net-next per device delete fix and hash based
  multipath patches
