yay.

instead of

	if (foo)
		return true;
	return false;

These could be:

	return (pmlmeinfo->state & WIFI_FW_ASSOC_SUCCESS) &&
	       ((pmlmeinfo->state & 0x03) == WIFI_FW_STATION_STATE);

and

	return (pmlmeinfo->state & WIFI_FW_ASSOC_SUCCESS) &&
	       ((pmlmeinfo->state & 0x03) == WIFI_FW_ADHOC_STATE);
