> 
> This patch adds a new benchmarking mode, which is intended for
> microbenchmarking individual parts of the cryptodev framework,
> specifically crypto ops alloc-build-free, cryptodev PMD enqueue and
> cryptodev PMD dequeue.
> 
> It works by first benchmarking crypto operation alloc-build-free loop (no
> enqueues/dequeues happening), and then benchmarking enqueue and
> dequeue separately, by first completely filling up the TX queue, and then
> completely draining the RX queue.
> 
> Results are shown as cycle counts per alloc/build/free, PMD enqueue and
> PMD dequeue.
> 
> One new test mode is added: "pmd-cyclecount"
>   (called with --ptest=pmd-cyclecount)
> 
> New command-line argument is also added:
>   --pmd-cyclecount-delay-ms: this is a pmd-cyclecount-specific parameter
>       that controls the delay between enqueue and dequeue. This is
>       useful for benchmarking hardware acceleration, as hardware may
>       not be able to keep up with enqueued packets. This parameter
>       can be increased if there are large amounts of dequeue
>       retries.
