Hello Oleg,

What I'm doing to hit this bug is to run the test script that is
available at https://github.com/bvanassche/srp-test on a setup that is
equipped with at least one InfiniBand adapter. I see the following
possibilities for you to reproduce this:
* Ask a colleague for access to an IB setup.
* Add RoCE support to the srp-test script and run that script against a
v4.8 kernel + ib_srp-backport + SCST ib_srpt drivers. These last two
(out-of-tree) drivers namely support SRP over RoCE. The upstream
drivers not yet. The SRP-over-RoCE functionality will be sent
upstream as soon as standardization of this protocol by the T10
committee has finished (this work has already been started and will
probably be finished later this year).

Please let me know if you need more information.

Bart.
