Hi , I am creating KNI interface and getting the following error when trying to config IP address. rte_kni_init rte_kni_alloc rte_kni_register_handlers all went through fine. the call back reg for if UP/down is never getting called. What am i missing ? ** the eth_dev here is created with "rte_eth_from_rings". does that make a diff ?
