Stephen,
 

Did you mean that the #= 255 limit is set in 2.4 Kernel, not
bridge-utility? I am wondering why t= here is such limit,
performance-related, or...? If I have to modify kernel 2.4 to exceed th= e
limit, can you tell me where I should look at? Any drawback if I incre= ase the limit up to 6000?

Many thanks

You can have up 1023 interfaces wit= h 2.6.  I didn't want to change the
2.4
code, only critical= bug fixes get backported.
