However, there are two problems with the rx_bytes statistics of the current enetc driver. one is that the length of VLAN header is not counted if the VLAN extraction feature is enabled. The other is that the length of L2 header is not counted, because eth_type_trans() is invoked before updating rx_bytes which will subtract the length of L2 header from skb->len. BTW, the rx_bytes statistics of XDP path also have similar problem, I will fix it in another patch.
