+*  CPUSaver parameters
+*
+*  All CPUSaver parameters are 16-bit literals that are part of a
+*  "move immediate value" instruction.  By changing the value of
+*  the literal in the instruction before the code is loaded, the
+*  driver can change the algorithm.
+*
+*  INTDELAY - This loads the dead-man timer with its inital value.
+*    When this timer expires the interrupt is asserted, and the 
+*    timer is reset each time a new packet is received.  (see
+*    BUNDLEMAX below to set the limit on number of chained packets)
+*    The current default is 0x600 or 1536.  Experiments show that
+*    the value should probably stay within the 0x200 - 0x1000.
+*
+*  BUNDLEMAX - 
+*    This sets the maximum number of frames that will be bundled.  In
+*    some situations, such as the TCP windowing algorithm, it may be
+*    better to limit the growth of the bundle size than let it go as
+*    high as it can, because that could cause too much added latency.
+*    The default is six, because this is the number of packets in the
+*    default TCP window size.  A value of 1 would make CPUSaver indicate
+*    an interrupt for every frame received.  If you do not want to put
+*    a limit on the bundle size, set this value to xFFFF.
+*
+*  BUNDLESMALL - 
+*    This contains a bit-mask describing the minimum size frame that
+*    will be bundled.  The default masks the lower 7 bits, which means
+*    that any frame less than 128 bytes in length will not be bundled,
+*    but will instead immediately generate an interrupt.  This does
+*    not affect the current bundle in any way.  Any frame that is 128
+*    bytes or large will be bundled normally.  This feature is meant
+*    to provide immediate indication of ACK frames in a TCP environment.
+*    Customers were seeing poor performance when a machine with CPUSaver
+*    enabled was sending but not receiving.  The delay introduced when
+*    the ACKs were received was enough to reduce total throughput, because
+*    the sender would sit idle until the ACK was finally seen.
+*
+*    The current default is 0xFF80, which masks out the lower 7 bits.
+*    This means that any frame which is x7F (127) bytes or smaller
+*    will cause an immediate interrupt.  Because this value must be a 
+*    bit mask, there are only a few valid values that can be used.  To
+*    turn this feature off, the driver can write the value xFFFF to the
+*    lower word of this instruction (in the same way that the other
+*    parameters are used).  Likewise, a value of 0xF800 (2047) would
+*    cause an interrupt to be generated for every frame, because all
+*    standard Ethernet frames are <= 2047 bytes in length.
