I would like to ask, can CX6 use TCP header/data split? Can you share your CX6's mlx driver information and FW information? I will test it. If CX6 can support, this one is even better for me. Thanks. I'll double check with David, but this is a typo here and needs to say CX7, the af-xdp work was done on CX6. So we'll correct in v2, thanks (& sorry for the confusion)!
