 * <b>non-interferential</b> (it will not change any frames) as possible:
 * - the port VLAN ID (VID) is set to 0
 * - the Ingress acceptable frame filter is set to accept all frames
 * - the VLAN port membership is set to the complete VLAN range (0 - 4094)
 * - the Ingress tagging mode is set to pass-through (will not change frames)
 * - the Egress tagging mode is to send tagged frames in the entire VLAN range (0 - 4094)
 *
 * Note that further disabling and re-enabling the VLAN feature for a given port will not reset the port VLAN behavior
 * to the settings listed above. Any VLAN settings made by the user are kept.
