+* 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.
