/*
 * 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
