From aee6c97f006cea7b1c791b21b222442437ee5403 Mon Sep 17 00:00:00 2001 From: Ciara Loftus Date: Thu, 3 May 2018 14:17:03 +0100 Subject: [PATCH] net/vhost: initialise device as inactive rte_eth_vhost_get_vid_from_port_id returns a value of 0 if called before the first call to the new_device callback. A vid value >=0 suggests the device is active which is not the case in this instance. Initialise vid to a negative value to prevent this.
