The HW that I am working with is ConnecX-6 Dx, which supports inline crypto and can send the data on the fabric at the same time. This patchset is based on v5.16-rc4 with Eric Biggers patches of the HW wrapped keys. It can be retrieved from branch "wip-wrapped-keys" at https://git.kernel.org/pub/scm/fs/fscrypt/fscrypt.git I tested this patch with modified nvme-rdma as the block device and created a DM crypt on top of it. I got performance enhancement compared to SW crypto. I tested the HW wrapped inline mode with the HW and the standard mode with a fallback algorithm.
