 * By adding a port into another port's dependency map the target port
 * 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

 *
 * @brief Enables or disables one or more EthDB features
 *
 * Selects one or more features (see @ref ixEthDBFeatureCapabilityGet for a description of the supported
 * features) to be enabled or disabled on the selected port (or all the ports).
 *
 * Note that some features are mutually incompatible:
 * - IX_ETH_DB_FILTERING is incompatible with IX_ETH_DB_WIFI_HEADER_CONVERSION
 *
 * Also note that some features require other features to be enabled: 
 * - IX_ETH_DB_FILTERING requires IX_ETH_DB_LEARNING
 *
 * This function will either enable the entire selected feature set for the selected port (or all the ports),
 * in which case it will return IX_ETH_DB_SUCCESS, or in case of error it will not enable any feature at all
 * and return an appropriate error message.
 *
 * The following features are enabled by default (for ports with the respective capability), 
 * for compatibility reasons with previous versions of CSR:
 * - IX_ETH_DB_LEARNING
 * - IX_ETH_DB_FILTERING
 *
 * All other features are disabled by default and require manual enabling using ixEthDBFeatureEnable.
 *
 * <b>Default settings for VLAN, QoS, Firewall and WiFi header conversion features:</b>
 *
 * <i>VLAN</i>
 *
 * 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.
 *
 * <i>QoS</i>
 *
 * The following default priority mapping table will be used (as per IEEE 802.1Q and IEEE 802.1D):

 * This means the firewall will not filter any frames until the feature is configured and the firewall table is
 * downloaded to the NPE.
 *
 * <i> Spanning Tree </i>
 *
 * The port is set to <b>STP unblocked mode</b>, therefore it will accept all frames until re-configured.

 * - IX_ETH_DB_WIFI_RECORD requires the MAC address and the portID
 * - IX_ETH_DB_FIREWALL_RECORD requires the MAC address and the portID
 *
