From 950d94ba0671e7f154a9e87a277f8efbddcee28f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Wed, 27 Jul 2016 01:15:25 +0400 Subject: vhost: add vhost_net_set_backend() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Not all vhost-user backends support ops->vhost_net_set_backend(). It is a nicer to provide an assert/error than to crash trying to call. Furthermore, it improves a bit the code by hiding vhost_ops details. Signed-off-by: Marc-André Lureau Reviewed-by: Michael S.
