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.
Thanks for letting me know this.
