/*
DESCRIPTION
This is the WRS-supplied configuration module for the VxWorks dec21x40End (dc)
END driver.  It has routines for initializing device resources and provides
BSP-specific routines for Intel (formerly DEC) 21040, 21140, and 21143
Ethernet PCI bus controllers found on the system.

The number of supported devices that can be configured for a particular system
is finite and is specified by the DEC21X40_MAX_DEV configuration constant.
This value, and the internal data structures using it, can be modified in this
file for specific implementations.

NOTE
This module has only been tested with the following Ethernet cards:

.IP "21040 controller"
Digital DE435.
.IP "21140 controller"
D-Link DFE-500TX and Kingston KNE-100TX.
.IP "21143 controller"
Intel (formerly DEC) EB143 evaluation card, Kingston KNE-100TX, and
Longshine 8038 TXD.
.LP

* sysDec21x40EndLoad - create a load string and load an dec21x40End device
*
* This routine will be invoked by the MUX for the purpose of loading an
* dec21x40End (dc) device with initial parameters.  This routine is
* constructed as an interface wrapper for the driver load routine.  Thus,
* the arguments and return values are consistent with any xxxEndLoad()
* routine defined for an END driver and the MUX API.
*
* INTERNAL
* The muxDevLoad() operation calls this routine twice.  A zero length
* <pParamStr> parameter string indicates that this is the first time
* through this routine.  The driver load routine should return the
* driver name in <pParamStr>.
*
* On the second pass though this routine, the initialization parameter
* string is constructed.  Note that on the second pass, the <pParamStr>
* consists of a colon-delimeted END device unit number and rudimentary
* initialization string (often empty) constructed from entries in the
* BSP END Device Table such that:
*
*     <pParamStr> = "<unit>:<default initialization string>"
*
* In the process of building the rest of <pParamStr>, the prepended unit
* number must be preserved and passed to the driver load routine.  The
* <default initialization string> portion mentioned above is discarded,
* but future versions of this routine may use it.
*
* The complete dec21x40End driver load string has format:
*
*     <unit>:<device_addr>:<PCI_addr>:<ivec>:<ilevel>:
*     <num_rds>:<num_tds>:<mem_base>:<mem_size>:<user_flags>
*
* RETURNS: An END object pointer, or NULL on error, or 0 and the name of the
* device if the <pParamStr> was NULL.
