Currently the task and buffer pools are hardcoded to

per channel to 256 since we need both source and
destination buffers from the buffer pool. So make

particularly interesting test, since the kernel I/OAT driver is totally
inaccessible from user-mode code (it is only exposed to the in-kernel

Maintaining an out-of-tree kernel driver for the sole purpose of
benchmarking is out of scope for the SPDK project, so remove the kperf
