Does Linux have some kind of RDMA emulation for "normal" network cards

NFSv4.1/RDMA testing?
Linux has a software iWARP emulation that works with standard Ethernet
devices. I use this with NFS/RDMA in test scenarios all the time. The
driver name is "siw".
Linux also has a software RoCE emulation, same deal, but I don't use it.
The driver name is "rxe".
For the record, both siw and rxe are not emulations, they're the
real thing and they interoperate with either software and hardware
implementations across the wire. They actually work well!
