     * Intel (R) IXP400 Software NPE Image ID Definition
     *
     * Firmware Id's for current firmware image.  These are typed by
     * NPE ID and the feature set.  Not all features are available
     * on all NPE's.  The Image ID has the following structure:
     *
     * Field                [Bit Location]
     * -----------------------------------
     * Device ID            [28..31]
     * NPE ID               [24..27]
     * NPE Functionality ID [16..23]
     * Major Release Number [8..15]
     * Minor Release Number [0..7]
     *
     * The following "feature sets" are known to exist:
     *
     * HSS-0: supports 32 channelized and 4 packetized.
     * HSS-0 + ATM + SPHY:
     *    For HSS, 16/32 channelized and 4/0 packetized.
     *    For ATM, AAL5, AAL0 and OAM for UTOPIA SPHY, 1 logical port, 32 VCs.
     *    Fast Path support.
     * HSS-0 + ATM + MPHY:
     *    For HSS, 16/32 channelized and 4/0 packetized.
     *    For ATM, AAL5, AAL0 and OAM for UTOPIA MPHY, 1 logical port, 32 VCs.
     *    Fast Path support.
     * ATM-Only:
     *    AAL5, AAL0 and OAM for UTOPIA MPHY, 12 logical ports, 32 VCs.
     *    Fast Path support.
     * HSS-2:
     *    HSS-0 and HSS-1.
     *    Each HSS port supports 32 channelized and 4 packetized.
     * ETH: Ethernet Rx/Tx which includes:
     *    MAC_FILTERING, MAC_LEARNING, SPANNING_TREE, FIREWALL
     * ETH+VLAN Ethernet Rx/Tx which includes:
     *    MAC_FILTERING, MAC_LEARNING, SPANNING_TREE, FIREWALL, VLAN_QOS
     * ETH+VLAN+HDR: Ethernet Rx/Tx which includes:
     *    SPANNING_TREE, FIREWALL, VLAN_QOS, HEADER_CONVERSION
