From a5d4742d152fbff5b5b279d8e9b592d5f35e31e4 Mon Sep 17 00:00:00 2001 From: Jerin Jacob Date: Fri, 3 Mar 2017 22:57:49 +0530 Subject: [PATCH] event/octeontx: add vdev interface functions ssovf and ssowvf PCIe VF devices are shared between eventdev PMD and ethdev PMD. This patch expose a set of interface API to get info about probed ssovf and ssowvf VF resources to use with eventdev and ethdev vdev devices latter.
