ice: Add support for packet mirroring using hardware in switchdev mode
Switchdev mode allows to add mirroring rules to mirror incoming and
outgoing packets to the interface's port representor. Previously, this was
available only using software functionality. Add possibility to offload
this functionality to the NIC hardware.
Introduce ICE_MIRROR_PACKET filter action to the ice_sw_fwd_act_type enum
to identify the desired action and pass it to the hardware as well as the
VSI to mirror.
Example of tc mirror command using hardware:
tc filter add dev ens1f0np0 ingress protocol ip prio 1 flower src_mac
b4:96:91:a5:c7:a7 skip_sw action mirred egress mirror dev eth1
ens1f0np0 - PF
b4:96:91:a5:c7:a7 - source MAC address
eth1 - PR of a VF to mirror to
