Stephen,

Thanks for your quick respond.

What do you mean by "later kernels"? I curently use kernel 2.4.20
Can I add a ioctl that enables modifying the bridge MAC address?

Thanks,
  Ariel

It's part of the Spanning Tree Protocol in the 802.1d standard.
In later kernels you can reset the address to be the same as any
of the interfaces being bridged.
