net: moxa: Use net_device_stats from struct net_device
Instead of using a private copy of struct net_device_stats in struct moxart_mac_priv_t, use stats from struct net_device. Also remove the now unnecessary .ndo_get_stats function. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
