net/mlx5e: Add VLAN offloads statistics
The following counters are now exposed through ethtool -S:
rx[i]_removed_vlan_packets (per channel)
rx_removed_vlan_packets
tx[i]_added_vlan_packets (per channel)
tx_added_vlan_packets
rx_removed_vlan_packets: The number of packets that had their
outer VLAN header stripped to the CQE by the hardware.
tx_added_vlan_packets: The number of packets that had their
outer VLAN header inserted by the hardware.
