ath6kl: implement ethtool stats
This supports a way to get target stats through normal ethtool stats API. For instance: # ethtool -S wlan1 NIC statistics: tx_pkts_nic: 353 tx_bytes_nic: 25142 rx_pkts_nic: 6 rx_bytes_nic: 996 d_tx_ucast_pkts: 89 d_tx_bcast_pkts: 264 d_tx_ucast_bytes: 3020 d_tx_bcast_bytes: 22122 ...
