Token Ring and Fiber Distributed Data Interface Device Types

Support for token ring (DL_TPR) and Fiber Distributed Data Interface (FDDI) device types in generic LAN driver (GLD) might be removed in a future Solaris release. After the removal is implemented, drivers for token ring or FDDI that rely on this support in GLD cease to function. However, other drivers or applications that do not use this support are not affected. To test whether a driver relies on GLD, run the following script:

#!/bin/sh
#
# Test a driver binary for use of GLD
#
for file
do
 	/usr/ccs/bin/nm $file | /bin/awk '
 	/\|gld_register$/       { isgld=1; }
 	END {
 		if (isgld)
 			print file, "uses GLD";
 		else
 			print file, "does not use GLD";
 	}' file=$file
done
