Hi, I use VPP with DPDK driver for I/O with NIC. For high speed switching of packets to and from kernel, I use DPDK KNI (kernel module and user space API's provided by DPDK) This works well because the vlib buffer is backed by the DPDK mbuf (KNI uses DPDK mbuf's)
Now, if I choose to use a native driver of VPP for I/O with NIC, is there a native equivalent in VPP to replace KNI as well ? The native equivalent should not lose out on performance as compared to KNI so I believe the tap interface can be ruled out here. If I keep using DPDK KNI and VPP native non-dpdk driver, then I fear I would have to do a data copy between the vlib buffer and an mbuf in addition to doing all the DPDK pool maintenance etc. The copies would be destructive for performance surely. So I believe, the question is -- in presence of native drivers in VPP, what is the high speed equivalent of DPDK KNI. Regards -Prashant
