[PATCH] net/ice: support traffic to original DCF port

[Zhichao Zeng]

Add support for sending traffic to the original DCF port
with 'port_representor' action by using DCF port id as 'port_id'.

For example:
testpmd> flow create 0 ingress pattern any
         / end actions port_representor port_id 0 / end
