 * filtering data will import the filtering data from the port it depends on.
 * Any changes to filtering data for a port - such as adding, updating or removing records -
 * will trigger updates in the filtering information for all the ports depending on
 * on the updated port.
 *
 * For example, if ports 2 and 3 are set in the port 0 dependency map the filtering
 * information for port 0 will also include the filtering information from ports 2 and 3.
 * Adding a record to port 2 will also trigger an update not only on port 2 but also on
 * port 0.
 *
 * The dependency map is a 256 bit array where each bit corresponds to a port corresponding to the
 * bit offset (bit 0 - port 0, bit 1 - port 1 etc). Setting a bit to 1 indicates that the corresponding

 * Note that the last bit (offset 255) is reserved and should never be set (it will be automatically

 * This feature can be used in the situation when a multi-port device (e.g. a switch) 
 * is connected to an IXP4xx port and the device can provide incoming frame port 
 * identification by tagging the TPID field in the Ethernet frame. Enabling
 * port extraction will instruct the NPE to copy the TPID field from the frame and 
 * place it in the <i>ixp_ne_src_port</i> of the <i>ixp_buf</i> header. In addition,
 * the NPE restores the TPID field to 0.
 *
 * If the frame is not tagged the NPE will fill the <i>ixp_ne_src_port</i> with the 
 * port ID of the MII interface the frame was received from.
 *
 * The TPID field is the least significant byte of the type/length field, which is

 *
 * When the VLAN/QoS feature is enabled for a port for the first time the default VLAN behavior 
 * of the port is set to be as <b>permissive</b> (it will accept all the frames) and 
 * <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.
 *
