01d,10mar97,dat  comments from reviewers
01c,28jan97,dat  fixed title line, added some comments.
01b,17jan97,dat  removed sysBusXxx, added sysNetHwInit2() and INCLUDE_NETWORK

DESCRIPTION
This library contains board-specific routines for network subsystems.

The generic network interface drivers each require different routines
from the BSP. For example, the if_ei driver (Intel 82596 Ethernet)
requires seven BSP support routines to be defined. Consult the reference
entry of the appropriate driver for details.

Note: Generic network interface drivers are not provided in source
code form; therefore they are not #included.

* sysNetHwInit - initialize the network interface

* This routine initializes the network hardware to a quiescent state.  It
* does not connect interrupts.
*
* Only polled mode operation is possible after calling this routine.
* Interrupt mode operation is possible after the memory system has been
* initialized and sysNetHwInit2() has been called.
