commit 7df5edbb427c79337bdd651c2bcdda8eb05f077b
Author: Lee Duncan <lduncan@suse.com>
Date:   Mon Sep 24 16:30:34 2018 -0700

    Fix incorrect sysfs logic for port and ip address.
    
    If "port" is available and "persistent_port" is not, then
    correctly use the one that is present for both values.
    Likewise for "address" and "persistent_address".
