I’m confused. I’ve seen multiple places on the internet that cards starting from ConnectX-4 have hardware flow offload functionality. Especially NAT44 offloading. I have ConnectX-5 MCX516A-CCAT where hardware NAT and offloading is even mentioned in datasheet but have trouble running it with nft flowtables.
Can anyone give me a binding answer if it is supported and worth trying ? I can provide more information about my config but for now i have doubts if it is even supported by this card.

Thank you for posting your query on NVIDIA Community.
Hardware Offload is supported on ConnectX-5 HCA. I would like to confirm if you are using MLNX OFED driver. If not, please install the driver by downloading the driver relevant to the OS in use —> Linux InfiniBand Drivers
