Hi，vpp experts I have a task that send one packet to three NIC my method is that use "vlib_buffer_alloc" function to copy three buffer，but this method is poor performance，about that if vpp is 10G bps， once copy will reduce 1.5G bps
is vpp has like dpdk buffer use refcnt count to avoid copy buffer？ can you give me some suggestions to send packet with high performence？ Best wish wanghe
