Here's a series that implements support for siw on tunnel devices,
based on suggestions from Jason Gunthorpe and Tom Talpey.

This series does not address a similar issue with rxe because RoCE
GID resolution behaves differently than it does for iWARP devices.
An independent solution is likely to be required for rxe.

Changes since v3:
- Clean up RCU dereference in cma_validate_port()

Changes since v2:
- Split into multiple patches
- Pre-initialize gid_attr::ndev for iWARP devices

      RDMA/siw: Fabricate a GID on tun and loopback devices
      RDMA/core: Set gid_attr.ndev for iWARP devices
      RDMA/cma: Deduplicate error flow in cma_validate_port()
      RDMA/cma: Avoid GID lookups on iWARP devices
