[Shally] Openssl supports both. Also, it provided as good example to demonstrate use-case to apps/PMDs that can support both.
>Will this work ok if there's a burst of ops including asym and sym operations >enqueued to the same qp? [Shally] first theoretical limitation in spec is not to send mix sym+asym to a single qp. Same limitation, I brought out in DPDK India summit talk as well. Thus, It is not proof-concepted in this patch of PMD. If required, a testcase can be added in subsequent versions as it is kind of advance test on openssl PMD and spec. >
