ll_temac: Reset dma descriptors indexes on ndo_open
[ 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.
