fjes: Enhance ethtool -S for fjes driver
This patch enhances ethtool -S for fjes driver so that EP related statistics can be retrieved. The following statistics can be displayed via ethtool -S: ep%d_com_regist_buf_exec ep%d_com_unregist_buf_exec ep%d_send_intr_rx ep%d_send_intr_unshare ep%d_send_intr_zoneupdate ep%d_recv_intr_rx ep%d_recv_intr_unshare ep%d_recv_intr_stop ep%d_recv_intr_zoneupdate ep%d_tx_buffer_full ep%d_tx_dropped_not_shared ep%d_tx_dropped_ver_mismatch ep%d_tx_dropped_buf_size_mismatch ep%d_tx_dropped_vlanid_mismatch Signed-off-by: Taku Izumi <izumi.taku@jp.fujitsu.com> Signed-off-by: David S.
