    Update interface sorting to handle pci ifaces last

    Because configuring sriov interfaces trigger a reapply of the puppet
    manifest, they should only be done after the management interface, so
    that there is no loss of connectivity when updating the management
    network, if the address is not added to the new management interface
    when runtime manifest is applied for puppet.
