Unloading

The driver should be able to sustain heavy driver activity, followed by module unload, without errors or memory leaks. This can be loop tested as follows (using C shell):

% while 1
<run driver test>
modunload -i  <module number>
> end

Alternatively:

% while 1

add_drv  driver name
<run driver test>
rem_drv driver name
> end
