    "scope" conversion only just before pyroute2 method call
    
    In "IpAddrCommand.list" method, the "scope" parameter is a string
    ("link", "site", "global" or "host"). This method will retrieve all
    devices with an IP address calling "ip_lib.get_devices_with_ip".
    
    Since [1], "ip_lib.get_devices_with_ip" makes the conversion of
    "scope" string parameter to pyroute2 format (see
    "pyroute2.netlink.rtnl.rtscopes"). The list command should skip then
    the previous conversion.

Title:
  Linuxbridge agent NetlinkError: (13, 'Permission denied') after Stein
  upgrade

Status in neutron:
  Fix Released

Bug description:
  OpenStack-Ansible deployment, just upgraded to Stein, using Ubuntu
  18.04.

  Neutron Linuxbridge agent logs keep complaining about NetlinkError: (13, 'Permission denied').
  After enabling debug, we actually see two stack traces, one happening in privsep, see log attached.

  We found out disabling IPv6 on the host workarounds the problem, but
  that's not a proper fix of course.
