You probably want to use vlib_buffer_clone() instead.

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
