  perfection is reached, not when there is no longer anything to add, but when
      there is no longer anything to take away    antoine de saint-exupery
>Environment:

not relevant (FreeBSD 2.1.0-RELEASE)

	

>Description:

if you have loaded one of the above modules (maybe there are more of them) you
can't modunload 'em - modunload then says device busy - i think it's not
really a bug - but it would be good if they would be unloadable (i.e. real
loadable modules) - i think in linux you can unload also such if_xx modules

	

>How-To-Repeat:

modload an if_sl module and try to modunload it then

	

>Fix:
	
don't know

State-Changed-By: wollman 
State-Changed-When: Sun Feb 4 12:31:30 PST 1996 
State-Changed-Why:  
t is not possible in the present networking framework to track down 
and neutralize all references to an interface; therefore, all interfaces 
will remain un-unloadable for the forseeable future.
