If member's can please provide some pointer on below point : 1) NUMA socket -1 I am trying to understand DPDK using testpmd. When i execute testpmd , i am getting the below message . Are these normal message or something is wrong in my setup EAL: PCI device 0000:00:1f.6 on NUMA socket -1 EAL: Invalid NUMA socket, default to 0 2) What is the memory-channels parameter usage ,which is being passed to testpmd. 3) Do we have any logical loopback mode in DPDK? So that we can try tx & rx logically without being dependent on hardware ports 4) How to know if the ethernet should be binded to IGB-UIO or VFIO module As of now , i try both & continue with which doesn't throw errors. I am reading the Documentation but felt short for these aspects & hence thought to check with the community for any pointers / guidance. Apologies if these are vary basic in nature as i am just starting with DPDK environment Thanks , Ashish
