Dear all,
I'm a DPDK newbie, but I hope anyway you are gonna consider my
comments or help me to understand the code a little bit better.
1) Aren't you updating the variable two times? for example, in
'acc100_enqueue_enc_cb',
you update both 'enqueued_count' and 'enqueue_err_count' and
then you call
'acc_update_qstat_enqueue' which does exactly the same thing but also updates
'enqueue_depth_avail'.
2) You reset the queue stats when '*_queue_stop' is called, wouldn't be better to reset the statistics when a queue is started? so that, if I want, I can still access the statistics of a stopped queue to see the counters.
All the best, Mattia
