[SPDK] Re: For Dummies guide to setting up ramdisk NVMe/TCP target

Hi Eric,

For the scenario that you've described three links would provide best pointers:
- https://spdk.io/doc/getting_started.html for SPDK itself
- https://spdk.io/doc/bdev.html#bdev_config_malloc to create malloc bdev
- https://spdk.io/doc/nvmf.html#nvmf_config to setup the NVMe/TCP target
Above would provide NVMe-oF target ready to connect initiator.

After that you can use another instance of SPDK to connect via NVMe/TCP initiator.
For RPC https://spdk.io/doc/bdev.html#bdev_config_nvme, but other apps like ./build/examples/perf work too.

CI for SPDK runs per-patch testing contained within single machine,
so ./test/nvmf/* scripts can be great examples for development.

The scenario you are describing is part of:
sudo ./test/nvmf/target/nvmf_example.sh --transport=tcp --iso

Thanks,
Tomek
