From 924da8f1c4f50ac2c45a2335cb2d5ff9616fc8e9 Mon Sep 17 00:00:00 2001 From: Steven Luong Date: Tue, 1 Aug 2017 09:17:36 -0700 Subject: [PATCH] net/virtio-user: send kick notify backend on init Acccording to the vhost-user spec [0], client must start ring upon receiving a kick (that is, detecting that file descriptor is reachable) on the descriptor specified by VHOST_USER_SET_VRING_KICK. The code sends a kick to the rx queue. It is missing sending a kick for the tx queue. This patch is to add the missing code to comply with the spec.
