Wow!  Well, that's very convenient for driver writers, so I'm pleased,
and I can update the docs.  It surprises me, though, to find out that
/sys/module is for things other than modules.

The correction below follows and depends on patch 1 of the six.


fix docs: built-in driver can use files in /sys/module

   It's helpful to trigger discovery after setting the list of allowed
   interfaces.  The aoetools package provides an aoe-discover script
