NFT Flowtable HW Offload

[Martin Zaharinov <micron10@xxxxxxxxx>]

Hi 


I try to run offload table in hw mode

but receive this error when try to load rule

./test-nft:125:19-25: Error: Could not process rule: Operation not supported
        flowtable testflow {
                  ^^^^^^^
./test-nft:134:48-64: Error: Could not process rule: No such file or directory
                ip protocol { tcp, udp, icmp } flow add @testflow;
                                               ^^^^^^^^^^^^^^^^^



this is rule :


table inet filter {
        flowtable testflow {
                hook ingress priority 0
                devices = { eth0, eth1 };
                flags offload;
        }

        chain forward {
                type filter hook forward priority -400; policy accept;
                ip protocol { tcp, udp, icmp } flow add @testflow;
                
        }
}



Receive Ethernet card : Mellanox Technologies MT27800 Family [ConnectX-5]

This is Mellanox ConnectX5 100Gbe Dual port card, MCX516A-CCAT

I think this card support hw offload ,
Kernel is 6.1.1 

How to enablee hw offload is there need other config ?

Best Regards,
Martin
