   33  * Firmware Id's for current firmware image.  These are typed by
   34  * NPE ID and the feature set.  Not all features are available
   35  * on all NPE's.  The Image ID has the following structure:
   36  *
   37  * Field                [Bit Location]
   38  * -----------------------------------
   39  * Device ID            [28..31]
   40  * NPE ID               [24..27]
   41  * NPE Functionality ID [16..23]
   42  * Major Release Number [8..15]
   43  * Minor Release Number [0..7]
   44  *
   45  * The following "feature sets" are known to exist:
   46  *
   47  * HSS-0: supports 32 channelized and 4 packetized.
   48  * HSS-0 + ATM + SPHY:
   49  *    For HSS, 16/32 channelized and 4/0 packetized.
   50  *    For ATM, AAL5, AAL0 and OAM for UTOPIA SPHY, 1 logical port, 32 VCs.
   51  *    Fast Path support.
   52  * HSS-0 + ATM + MPHY:
   53  *    For HSS, 16/32 channelized and 4/0 packetized.
   54  *    For ATM, AAL5, AAL0 and OAM for UTOPIA MPHY, 1 logical port, 32 VCs.
   55  *    Fast Path support.
   56  * ATM-Only:
   57  *    AAL5, AAL0 and OAM for UTOPIA MPHY, 12 logical ports, 32 VCs.
   58  *    Fast Path support.
   59  * HSS-2:
   60  *    HSS-0 and HSS-1.
   61  *    Each HSS port supports 32 channelized and 4 packetized.
   62  * ETH: Ethernet Rx/Tx which includes:
   63  *    MAC_FILTERING, MAC_LEARNING, SPANNING_TREE, FIREWALL
   64  * ETH+VLAN Ethernet Rx/Tx which includes:
