Problem Description:

1047118 fddi not working with SunOS 4.1.1

The patch is in the form of two object files, one set per OS/arch
combination.

The files are:	if_fddi.o and if_fddi_subr.o

The OS/arch combinations provided are:

	sun3/4.1, sun3/4.1.1
	sun4/4.1, sun4/4.1.1, sun4/4.0.3 sun4-490/4.1_PSR_A

As compared to the FCS release tape, this patch fixes the following
problems:

	- Reinserts the NFS patch that was accidentally left out of 1.1
	- Fixes download behaviour so that FDDI will stay up with the
	  downloaded version of firmware, in spite of config-down
	  and config-up, as well as firmware timeouts.
	- SUPPORTS 4.1.1
	- No longer prints "Unsupported llc type XX" messages on console.
	- fixes  bug on 1.1 PATCH 2 on Sun4-470, Sun4-490 sudden increase in the number
	  of nfs read and getattr timeouts.


INSTALL:

 Copy the new version of if_fddi.o and if_fddi_subr.o into /sys/sun?/OBJ after
first saving the FCS versions.

AS ROOT:

 # mv /sys/sun?/OBJ/if_fddi.o /sys/sun?/OBJ/if_fddi.o.old
 # mv /sys/sun?/OBJ/if_fddi_subr.o /sys/sun?/OBJ/if_fddi_subr.o.old

 # cp sun?/4.X/if_fddi.o /sys/sun?/OBJ/if_fddi.o
 # cp sun?/4.X/if_fddi_subr.o /sys/sun?/OBJ/if_fddi_subr.o

Where the "?" will need to be replaced with your architecture type and the "X"
replaced with the SunOS version number. 
example  #cp sun4/4.1.1/if_fddi.o /sys/sun4/OBJ/if_fddi.o

then follow the System and Network Administration Manual or the FDDI instalation
section on installing and booting a new kernel.
