For FT2000+/64 devices,
when four virtual machines share the same physical network interface,
DROP will occur due to the single core CPU performance problem.
ip_check_defrag and macvlan_process_broadcast is on the same CPU.
When the MACVLAN PORT increases, the CPU usage reaches more than 90%.
bc_queue > bc_queue_len_used (default 1000), causing DROP.
