o reset ni_inact when ni_inact_reload is changed so we're assured a valid setting o never let ni_inact go negative o add a knob to disable hostap sta idle handling (e.g. so it can be done by a user application) o remove bogus reload on associate Reviewed by: avatar Approved by: re (blanket wireless)
