Subject: libertas driver carrier of signaling
Date: Wed, 16 Dec 2009 23:55:24 +0100	[thread overview]
Message-ID: <20091216225524.GD3788@sortiz.org> (raw)

Hi guys,

I was looking at the libertas driver and found that piece of code, at scan.c:

/* We want to scan all channels */
	chan_count = lbs_scan_create_channel_list(priv, chan_list);

	netif_stop_queue(priv->dev);
	netif_carrier_off(priv->dev);

So, why do we need to turn carrier off when scanning? I could barely see why
we'd want to stop the netdev tx queue, but is turning carrier off really
needed ?

Thanks in advance for your answers.

Cheers,
Samuel.
