Hi Manuel, This is likely a mismatch in VPP side. I only tested it with QAT (2 qps per VF) and SW cryptodevs (default 8 qps) at the time (over a year ago).
I only tested it with SW cryptodevs and QAT, that was the HW I had access to. So like I mentioned before, if you do not want to rework the code to support 1 qp per resource, then a check for at least 2 qps per device is required to use that device. I could provide a patch to use 1 pq per resource over the next few days if you are interested in it or could review if you decide to do the work. Which device do you want to use?

My concern was due to dpdk, since there are a few device drivers exporting only one queue pair for their crypto devices. (I followed the code assuming one qps, based on a dpdk-18.11 exported value) So I do not know where is the mismatching, vpp or dpdk? BR, Manuel
