  SVN rev 208213 on 2010-05-17 19:51:34Z by jhb
  
  Prevent unloading a kld for a driver that has subinterfaces (vlan and/or
  wlan interfaces) from being automatically reloaded via devd shutdown
  event handlers.
  - Revert part of my previous changes to call ifn_stop on subinterfaces
    when an interface is detached.  It is better to destroy the interfaces
    first so that an 'ifconfig foo0.blah down' doesn't result in ifconfig
    auto-loading if_foo.ko.  The ifconfig command will not be invoked if
    foo0.blah is gone when ifn_stop() is called.  Furthermore, it is not
    necessary to explicitly invoke ifn_stop() after the subinterface is
    destroyed as devd will already do that.
  - Pass -n to ifconfig when destroying interfaces so that destroying a
    cloned interface does not kldload any drivers.
