Subject: [dpdk-dev] [PATCH] net/vhost: Initialise vid to -1
Date: Fri, 27 Apr 2018 15:19:58 +0100 [thread overview]
Message-ID: <1524838798-5445-1-git-send-email-ciara.loftus@intel.com> (raw)
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.
