From e7b9d1d2806c6bb8f30922c3cd6736b3076b7ec2 Mon Sep 17 00:00:00 2001 From: Jiayu Hu Date: Mon, 31 Jul 2017 15:56:44 +0800 Subject: [PATCH] net/virtio: fix Rx interrupt setup When use rte_eth_dev_configure() to enable rx queue interrupt for virtio devices, virtio_init_device() isn't called to set up the interrupt environment, which causes rx queue interrupt setup failed. This patch is to fix this issue.
