From f9a09ca3ea69d108d828b7c82f1bd61b2df6fc96 Mon Sep 17 00:00:00 2001 From: Cindy Lu Date: Thu, 22 Dec 2022 15:04:48 +0800 Subject: vhost: add support for configure interrupt Add functions to support configure interrupt. The configure interrupt process will start in vhost_dev_start and stop in vhost_dev_stop. Also add the functions to support vhost_config_pending and vhost_config_mask.
