net/mlx5e: Support offload cls_flower with drop action
Parse tc_cls_flower_offload into device specific commands and program
the hardware to classify and act accordingly.
For example, to drop ICMP (ip_proto 1) packets from specific smac, dmac,
src_ip, src_ip, arriving to interface ens9:
# tc qdisc add dev ens9 ingress
# tc filter add dev ens9 protocol ip parent ffff: \
flower ip_proto 1 \
dst_mac 7c:fe:90:69:81:62 src_mac 7c:fe:90:69:81:56 \
dst_ip 11.11.11.11 src_ip 11.11.11.12 indev ens9 \
action drop
