[PATCH v7 0/7] blktests: Add support to run nvme tests with tcp/rdma transports

[Sagi Grimberg]

> We have a collection of nvme tests, but all run with nvme-loop. This
> is the easiest to run on a standalone machine. However its very much possible
> to run nvme-tcp and nvme-rdma using a loopback network. Add capability to run
> tests with a new environment variable to set the transport type $nvme_trtype.
> 
> $ nvme_trtype=[loop|tcp|rdma] ./check nvme
> 
> This buys us some nice coverage on some more transport types. We also add
> some transport type specific helpers to mark tests that are relevant only
> for a single transport.
> 
> Changes from v6:
> - fix _nvme_discover wrong use of subsysnqn that is never passed
> - move shellcheck fixes to the correct patches (not fix in subsequent patches)
> Changes from v5:
> - fix shellcheck errors
> Changes from v4:
> - removed extra paranthesis
> - load either rdma_rxe or siw for rdma transport tests
> Changes from v3:
> - remove unload_module from tests/srp/rc
> - fixed test run cmd
> Changes from v2:
> - changed patch 6 to move unload_module to common/rc
> - changed helper to be named _require_nvme_trtype_is_fabrics
> Changes from v1:
> - added patch to remove use of module_unload
> - move trtype agnostic logig helpers in patch #3

Omar, anything left on your end to take this?
