Problem Description:

This directory contains FDDI/S 1.0 patch for 
SunOS 4.1.x. It is compatible with and can be installed
on sun4c or sun4m architectures running SunOS 4.1.x.
It contains relevant software fixes to following bugs:

1089283	FDDI diskless, diskfull clients fail
1092718	FDDI panics C2 system
1095664 FDDI panics system when module is loaded.
1102727 patch 100706-01 has undefined symbol TREQ when 
		using a linkable driver
1113244 local host MAC address wrong when sending 
		broadcast packets
1123260 fddi-s goes down and the up continuously when 
                fragmented runt packets received.
1122938 Incorrect header (SNAP PROTOCOL ID) in FDDI 
                frames

where C2 = Campus 2.

Note that bugid 1092718 also involves hardware 
bug with Viking 1.2. (Viking 1.2/MXCC or Viking
2.x or above is required for FDDI).

Note that 1123260 is applicable to a ring which has
at least one PHY (physical layer) which can introduce
odd-symbol pairs on the medium. The variable 
bf_ignore_lem_noise has to be set to a non-zero value,
for the driver to workaround this bug. This variable
is set to 0 by default, and should normally be used
with this value.

Note that bugid 1122938 involves adding to the structure
bf_org_id variable to change the organization id of
for non-TCP/IP LLC frames transmitted via the NIT 
interface.  See bug report for more details.

In addition, this patch contains new detection of phy lock
condition in the device, and workarounds for some
diskless boot problems with the Sparcstation 10/Campus2.

In addition, this patch contains enhancements that may
result in improvements in memory to memory tcp/ip data
transfer performance for the SparcStation 2 machines.

In addition, this patch contains a working vmunix
for the Sparcstation 10 machine. (The vmunix supplied
with FDDI/S 1.0 release will not work on Sparcstation
10). This vmunix is located in sun4m/vmunix.bf.SS10,
and may be used for diskless boot of Sparcstation 10
clients.

It is assumed that the FDDI/S 1.0 FCS software
is already extracted from the regular media before
running the install script here. The install script
copies the patched binaries into the directory
where the FDDI/S 1.0 FCS software has already been
extracted (default is /usr/BF or /export/exec/sun4/BF).
After running the patch install script here, the 
install_bf script needs to be run from the FDDI/S 1.0 
FCS software package.

Note that the vmunix.bf.SS10 file is NOT copied by
the install script to the directory where the FDDI/S
1.0 FCS software has been extracted. It needs to be
copied to the appropriate location (e.g. the diskless
SS/10 client's root partition in the server) manually.
