Hello all,

Just tracing a bit the code I noticed that there is a concept of "queue pair" 
and every crypto device allocates its own number of queue pairs.
Two questions (version 19.01):
1. Regarding the max_res_idx (ipsec.c) calculation:
max_res_idx = (dev->max_qp / 2) - 1;   (if dev->max_qp == 1 then max_res_idx = 
65535)
Notice that if max_qp is 1 then the loop below never ends (since j is always <= 
65535)
u16 j;
 for (j = 0; j <= max_res_idx; j++, res_idx++) {
}

Another issue that I am trying to understand is the snippet below (ipsec.h):
   enq = rte_cryptodev_enqueue_burst (res->dev_id, res->qp_id + outbound,
res->ops, res->n_ops);

outbound == 1 in the enqueue case and crypto resources under that function call 
 have only  "res->gp_id" queue pairs ids, not sure how can it work(unless there 
is a contiguous allocation from another device)

I'd welcome any help on understanding both points.

BR,
Manuel
