[PATCH v6 0/7] blktests: Add support to run nvme tests with tcp/rdma transports

[Sagi Grimberg <sagi@grimberg.me>]

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 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

Sagi Grimberg (7):
  nvme: consolidate nvme requirements based on transport type
  nvme: consolidate some nvme-cli utility functions
  nvme: make tests transport type agnostic
  tests/nvme: restrict tests to specific transports
  nvme: support nvme-tcp when runinng tests
  common: move module_unload to common
  nvme: support rdma transport type
