BTW, is there a reason why the ifconfig source code can't compile in
Darwin when you're enabling the features to get the link speed?
Dunno. Can you give us a little more information about the
compilation errors you're seeing?
To sum-up, the ifconfig project is provided (or was provided when I
downloaded it in April 2003) with the media information off (i.e. the
media: information is not displayed when you call ifconfig -a)
A little investigation of the source code showed that there was a
USE_IF_MEDIA flag to define to get this information in the ifconfig.c
file => First conclusion, the version which is shipping with OS X is
not using this project settings.
When you define this flag in the ifconfig.c code (I'm doing it at line
96), you're ending with 5 errors and 2 warnings:
ifconfig.c:443: illegal expression, found `{'
ifconfig.c:221: parse error in conditional expression
ifconfig.c:701: warning: redefinition of macro MASK
/usr/include/ppc/param.h:120: warning: this is the location of the
previous definition
ifconfig.c:2223: illegal expression, found `if'
ifconfig.c:1111: parse error in conditional expression
cpp-precomp: warning: errors during smart preprocessing, retrying in
basic mode
(if you just compile the source code without adding the #define, it
builds with 4 warnings, 3 of them being a bit big and would not be
expected to exist).
=> Second conclusion: either I'm not doing the right thing, or the code
is not compiling with the media: info on.
