crypto: encrypt/decrypt queues sw_scheduler
Type: improvement Previously multiple sw crypto scheduler queues per core design caused unaverage frame processing rate for each async op ID – the lower the op ID is the highly likely they are processed first. For example, when a RX core is feeding both encryption and decryption jobs of the same crypto algorithm to the queues at a high rate, in the mean time the crypto cores have no enough cycles to process all: the jobs in the decryption queue are less likely being processed, causing packet drop. To improve the situation this patch makes every core only owning a two queues, one for encrypt operations and one for decrypt. The queue is changed either after checking each core or after founding a frame to process. All crypto jobs with different algorithm are pushed to thoses queues and are treated evenly. In addition, the crypto async infra now uses unified dequeue handler, one per engine. Only the active engine will be registered its dequeue handler in crypto main.
