Subject: [ 045/135] ll_temac: Reset dma descriptors indexes on ndo_open
Date: Fri, 11 Oct 2013 12:38:46 -0700 [thread overview]
Message-ID: <20131011193950.163462884@linuxfoundation.org> (raw)
In-Reply-To: <20131011193945.181603934@linuxfoundation.org>
3.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ricardo Ribalda <ricardo.ribalda@gmail.com>
[ Upstream commit 7167cf0e8cd10287b7912b9ffcccd9616f382922 ]
The dma descriptors indexes are only initialized on the probe function.
If a packet is on the buffer when temac_stop is called, the dma
descriptors indexes can be left on a incorrect state where no other
package can be sent.
So an interface could be left in an usable state after ifdow/ifup.
This patch makes sure that the descriptors indexes are in a proper
status when the device is open.
