How to use and config IPinIP offload on mcx555a-ecat ?

Hi, we will use IPinIP offload on mcx555a-ecat in any os. How to config it ? Thanks!

Are you means IP tunnel? You know, mellanox ETH NIC is L2 device, above layer like IP TCP and configuration depend on OS and L3 protocol stack implement.

I can’t see this feature list on our HW PB or driver user manual.
