 221  *      Currently they return the values of the first active physical port
 222  *      found. A set to the virtual port will actually change all active
 223  *      physical ports. A get returns the melted values of all active physical
 224  *      ports. If the port values differ a return value INDETERMINATED will

 256  *      -Fixed: On VPD key creation an invalid key name could be created
 257  *              (e.g. A5)
 258  *      -Some minor changes in comments and code.
 259  *
 260  *      Revision 1.47  1998/12/08 16:00:31  mhaveman

 264  *              returned and the rest of the buffer was filled with 0xff
 265  *      -Fixed: Mysteriously the preset on RLMT_MODE still returned
 266  *              BAD_VALUE.

 271  *              larger than SK_PNMI_MIN_STRUCT_SIZE the return value is stored
 272  *              to the buffer. In this case the caller should always return
 273  *              ok to its upper routines. Only if the buffer size is less
 274  *              than SK_PNMI_MIN_STRUCT_SIZE and the return value is unequal
 275  *              to 0, an error should be returned by the caller.
 276  *      -Fixed: Wrong number of instances with RLMT statistic.

1364  *                                    upper 32 bit of the 64 bit counter.
1365  *      SK_PNMI_EVT_SEN_XXX           The event is generated by the I2C module
1366  *                                    when a sensor reports a warning or
