Hello Dan,
Today running the srp-test software is only possible on a system
equipped with at least one InfiniBand port. Since the soft-RoCE driver
has been accepted in kernel v4.8 (drivers/infiniband/sw/rxe) it should
be possible to modify the srp-test software such that it runs on any
system equipped with at least one Ethernet port. However, that will
require adding RoCE (RDMA over Ethernet) support to the ib_srp and
ib_srpt drivers.
Bart.
