Yes. it does. Will resend with a small change fixing
an uninitialized variable I just invented with the patch (uuuhh).

I will attach Kamal's oops report, but his fix was
blocking allowed application behavior (setting some queue
sizes to zero). The intention of my patch is to fix siw
to handle that application behavior correctly. So the fixes
lines will be different.
 

Thanks,
Bernard.
