For these and for the rest of the SQ_SG_MODE devices, provide the appropiate polling routine that handles a single pair of Rx/Tx BD rings, removing the overhead incurred by the multiple queues/ multiple interrupt group devices (veTSEC/ eTSEC2.0 devices). So this is primarily a fix for the TSEC devices. Signed-off-by: Claudiu Manoil Signed-off-by: David S. Miller --- Reading git-diff-tree failed
