**
** PROC NAME: e100_handle_zlock
** This function manages a state machine that controls
** the driver's zero locking algorithm.
** This function is called by e100_watchdog() every ~2 second.
** States:
** The current link handling state is stored in
** bdp->zlock_state, and is one of:
** ZLOCK_INITIAL, ZLOCK_READING, ZLOCK_SLEEPING
** Detailed description of the states and the transitions
** between states is found below.
** Note that any time the link is down / there is a reset
** state will be changed outside this function to ZLOCK_INITIAL
** Algorithm:
** 1. If link is up & 100 Mbps continue else stay in #1:
** 2. Set 'auto lock'
** 3. Read & Store 100 times 'Zero' locked in 1 sec interval
** 4. If max zero read >= 0xB continue else goto 1
** 5. Set most popular 'Zero' read in #3
** 6. Sleep 5 minutes
** 7. Read number of errors, if it is > 300 goto 2 else goto 6
** Data Structures (in DRIVER_DATA):
** zlock_state - current state of the algorithm
** zlock_read_cnt - counts number of reads (up to 100)
** zlock_read_data[i] - counts number of times 'Zero' read was i, 0 <= i <= 15
** zlock_sleep_cnt - keeps track of "sleep" time (up to 300 secs = 5 minutes)
**
** Parameters: DRIVER_DATA *bdp
**
** bdp - Pointer to HSM's adapter data space
**
** Return Value: NONE
**
** See Also: e100_watchdog()

This file contains the loadable micro code arrays to implement receive
bundling on the D101 A-step, D101 B-step, D101M (B-step only), D101S,
D102 B-step, D102 B-step with TCO work around and D102 C-step.
Each controller has its own specific micro code array. The array for one
controller is totally incompatible with any other controller, and if used
will most likely cause the controller to lock up and stop responding to
the driver. Each micro code array has its own parameter offsets (described
below), and they each have their own version number.

/*************************************************************************
* 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 algorithm.
*
* CPUSAVER_DWORD - This is the location of the instruction that loads
* the dead-man timer with its inital value. By writing a 16-bit
* value to the low word of this instruction, the driver can change
* the timer value. The current default is either x600 or x800;
* experiments show that the value probably should stay within the
* range of x200 - x1000.
*
* CPUSAVER_BUNDLE_MAX_DWORD - This is the location of the instruction
* that 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.
*
* CPUSAVER_MIN_SIZE_DWORD - This is the location of the instruction
* that 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.
