gtpu: offload RX flow
ip4 gtpu cli/api (using flow infra) to create flows and enable them on
different hardware (currently tested with ice)
to offload a gtpu tunnel onto hw:
set flow-offload gtpu hw TwentyFiveGigabitEthernet3/0/0 rx gtpu_tunnel0
to remove offload:
set flow-offload gtpu hw TwentyFiveGigabitEthernet3/0/0 rx gtpu_tunnel0 del
