This resulted into kernel panic on the first VSI that didn't have any netdev associated to it. The DCB change notification to the client(s) should be done only once for the PF/LAN VSI where the client(s) instances have been added to. Also, move the notification call after the PF driver has made changes related to the updated DCB configuration.
