[PATCH v2 0/9] crypto/mlx5: support AES-GCM

[Suanming Mou]

Hi Akhil,

Maybe due to "To" is empty, it was not collected correctly to the ML. But it was in my inbox, and you were cced.

Thanks,
Suanming

> The crypto operations are performed with crypto WQE. If the input buffers(AAD,
> mbuf, digest) are not contiguous and there is no enough headroom or tailroom for
> AAD or digest, as the requirement from FW, an UMR WQE is needed to generate
> contiguous address space for crypto WQE.
> The UMR WQE and crypto WQE are handled in two different QPs.
> 
> The QP for UMR operation contains two types of WQE, UMR and SEND_EN WQE.
> The WQEs are built dynamically according to the crypto operation buffer address.
> Crypto operation with non-contiguous buffers will
> have its own UMR WQE, while the operation with contiguous buffers
> doesn't need the UMR WQE. Once the all the operations WQE in the enqueue
> burst built finishes, if any UMR WQEs are built, additional SEND_EN WQE will be
> as the final WQE of the burst in the UMR QP.
> The purpose of that SEND_EN WQE is to trigger the crypto QP processing with the
> UMR ready input memory address space buffers.

> The QP for crypto operations contains only the crypto WQE and the QP WQEs are
> built as fixed in QP setup. The QP processing is triggered by doorbell ring or the
