Re: [vpp-dev] vlib_buffer_clone behavior when trying to send to two interfaces

Before any clone, play with the buffer using vlib_buffer_advance() with a negative advance. Try first with negative 20 because 20 is size of an IP header with no options. You will see the output packet in tcpdump change. Then, see what is an appropriate advance for final code. Hemant Fro
