[PATCH blktests v3 4/4] nvme/047: Test different queue types for fabrics transports

[Daniel Wagner]

Test if the fabrics transports are handling different queues types
correctly.

Currently, only TCP and RDMA from the fabric transport family support
this feature, so limit the test to these two.

We also issue some I/O to make sure that not just the plain connect
works. For this we have to use a file system which supports direct I/O
and hence we use a device backend.
