> When performing an authentication verification, the PMD was using
> memory at the end of the input buffer, to store temporarily the digest.
> This operation requires the buffer to have enough tailroom unnecessarily.
> Instead, memory is allocated for each queue pair, to store temporarily the
> digest generated by the driver, so it can be compared with the one provided
> in the crypto operation, without needing to touch the input buffer.

Could you take a look at this patch?
The series have been acked by Fan Zhang, but this patch affects the ARMv8 PMD,
So I would prefer applying it after your review.
