[Bridge] Sparc Bridge problems

I was never able to get bridging working on the UltraSPARC architecture.
>From what I have gathered, there is some kind of issue between the 32bit
userland (brctl) and 64bit kernel.  If you use Debian, you can get a 64bit
version of brctl, but even with that I could never get it to work.  I could
never find anyone who has gotten it to work on the UltraSPARC/Sparc64

If you're a kernel hacker, you might be able to get some help debugging the
problems if you can suggest new code.  Otherwise you'll have to use an x86
based platform (there bridging works beautifully).

Perhaps with time this will bill sorted out in the 2.6 kernel???
