gianfar: Fix stats support
This patch updates the per rx/tx queue stats. To update the per rx queue stats a new structure has been introduced rx_q_stats. The per tx queue stats are updated via the netdev_queue structure itself. Note that we update only the tx_packtes, tx_bytes, rx_packets, rx_bytes and rx_dropped stats on a per queue basis.
