Hello Service_NVIDIA,
Thank you for posting your inquiry on the NVIDIA Developer Forum - Infrastructure and Networking - Section.
Unfortunately only the ConnectX-6 Dx Crypto versions support kTLS offload, as mentioned in the MLNX_OFED UG → Kernel Transport Layer Security (kTLS) Offloads - NVIDIA Docs
The following link provides the information which ConnectX-6 Dx OPNs have crypto functionality → NVIDIA ConnectX-6 Dx Ethernet Adapter Cards User Manual - NVIDIA Docs
Thank you and regards,
~NVIDIA Networking Technical Support
