[EXT] [PATCH v2 0/2] crypto/scheduler: add support for security protocols

[Anoob Joseph]

Hi David,

While it is desirable to add security under crypto/scheduler, would it be functionally possible if the PMDs perform stateful processing? For example, with lookaside protocol mode of IPsec, fields such as seq no & AR defines how the crypto operation can be performed. Without two PMDs sharing this (actively), how can the load balancing happen?

Said that, I agree utility of scheduler for stateless operations. My understanding is, PDCP offload that is available today is not stateful and that can leverage this. I'm not sure of DOCSIS and MACsec.

Should we make it such that only specific security sessions would be eligible for scheduler operation?

Thanks,
Anoob
