[dpdk-stable] [EXT] [dpdk-dev] [PATCH] crypto/mlx5: fix crypto QP indexing

[Akhil Goyal]

> The crypto QP consumer (ci) and producer (pi) indexes are increased
> with each successful enqueue/dequeue operations.
> 
> However the QP pi index is calculated with a wraparound the number
> of elements while the QP ci does not.
> 
> This is causing incorrect engine calculation for encqueued WQ values
> (wq->pi - wq->ci) and eventually the device stops accepting new enqueue
> operations.
> 
> Fixed by removing the wraparound on QP pi and using a temp calculation
> where wraparound values are needed.
> 
> Fixes: 8e196c08ab53 ("crypto/mlx5: support enqueue/dequeue operations")
