net: lan966x: Adjust maximum frame size when vlan is enabled/disabled
When vlan filtering is enabled/disabled, it is required to adjust the maximum received frame size that it can received. When vlan filtering is enabled, it would all to receive extra 4 bytes, that are the vlan tag. So the maximum frame size would be 1522 with a vlan tag. If vlan filtering is disabled then the maximum frame size would be 1518 regardless if there is or not a vlan tag. Fixes: 6d2c186a ("net: lan966x: Add vlan support.")
