Subject: NTB: reset tx_index on link toggle
From: Jon Mason <jon.mason@xxxxxxxxx>
commit 90f9e934647e652a69396e18c779215a493271cf upstream.
If the NTB link toggles, the driver could stop receiving due to the
tx_index not being set to 0 on the transmitting size on a link-up event.
This is due to the driver expecting the incoming data to start at the
beginning of the receive buffer and not at a random place.
