vxlan:offload RX flow
ip4 vxlan cli/api (using flow infra) to create flows and enable them on
different hardware (currently tested with i40e)
to offload a vxlan tunnel onto hw:
set flow-offload vxlan hw TwentyFiveGigabitEthernet3/0/0 rx vxlan_tunnel1
to remove offload:
set flow-offload vxlan hw TwentyFiveGigabitEthernet3/0/0 rx vxlan_tunnel1 del
