Subject: [net-next PATCH v3 2/3] ice: Enable RX queue selection using
 skbedit action

This patch uses TC skbedit queue_mapping action to support
forwarding packets to a device queue. Such filters with action
forward to queue will be the highest priority switch filter in
HW.
Example:
$ tc filter add dev ens4f0 protocol ip ingress flower\
  dst_ip 192.168.1.12 ip_proto tcp dst_port 5001\
  action skbedit queue_mapping 5 skip_sw

The above command adds an ingress filter, incoming packets
qualifying the match will be accepted into queue 5. The queue
number is in decimal format.

Refactored ice_add_tc_flower_adv_fltr() to consolidate code with
action FWD_TO_VSI and FWD_TO QUEUE.
