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
