2019-12-02 Thread Thomas Monjalon
Hi all, VPP has a buffer called vlib_buffer_t, while DPDK has rte_mbuf. Are there some benchmarks about the cost of converting, from one format to the other one, during Rx/Tx operations? I'm sure there would be some benefits of switching VPP to natively use the DPDK mbuf allocated in mempools. Wh
