Installation Notes for SVME178 FDDI Driver
------------------------------------------


Version      : 1.4
Release date : 1999-02-15

To build into kernel:
=====================

1.  Copy ccFddi.a to your BSP library directory
    (/tornado/target/config/svme178/lib).
2.  Edit the Makefile in the BSP directory (/tornado/target/config/svme178).
    Find the line
       MACH_EXTRA      =
    and replace with
       MACH_EXTRA      =  ./lib/ccFddi.a
3.  Add the following code fragment to config.h (before "#define
    DEFAULT_BOOT_LINE"):
       #define INCLUDE_FDDI
       #ifdef INCLUDE_FDDI
       #define NETIF_USR_DECL     IMPORT int ccfddiattach ();
       #define NETIF_USR_ENTRIES  { "fddi", ccfddiattach, /* Unit = */ 0, \
                               /* Receive buffers = */ 0 /* = use default */, \
                               /* Transmit buffers = */ 0 /* = use default */},
       #endif /* INCLUDE_FDDI */

4.  Rebuild all vxWorks images.

To load separately:
===================

From the vxWorks shell type:
       ld < ccFddi.a

Starting the driver:
====================

The driver is started with the ccfddiattach command. The syntax is as
follows:
   ccfddiattach unit, nReceiveBuffers, nTransmitBuffers
where:
   unit must be 0 (only one adapter is supported).
   nReceiveBuffers specifies the number of receive buffers to allocate.
        This is constrained to be in the range 10 - 100. If 0 is specified,
        a default value of 13 will be used.
   nTransmitBuffers specifies the number of transmit buffers to allocate.
        This is constrained to be in the range 10 - 100. If 0 is specified,
        a default value of 20 will be used.
WARNING: Changing any of these parameters from the default values may have
a profound effect on driver performance. Increasing the number of
allocated buffers may worsen driver performance in some situations.
