Re: [Bridge] Sparc Bridge problems

[Santiago Leon <santil@us.ibm.com>]

I had the exact same problem a while ago on a 64-bit PowerPC and hacked 
my way around it... (can't seem to find the patch now, though)...  The 
first thing you want to do is run:
brctl addbr br0
strace brctl addif br0 eth0

and look for what ioctl fails... Post that output and I might be able to 
point you to the solution...
