If so, is there any reason why that support/code shouldn't/couldn't be added to more ethernet devices? Certainly some of the more common/faster ones that many people are using, like bge (and wm, of course) it would be of value I'd think.The details are in http://mail-index.netbsd.org/tech-net/2010/03/24/msg001945.html and follow up. Basically agr(4) should use the same interface as the one used by ifconfig foo0 ether xx:xx:xx:xx:xx, but I don't know how to do this from the kernel.
I see. It looks like the "what is the way to do this" portion of the thread dropped after a bit.
If you pick that thread up again on tech-net, please Cc me. And whether we call ifioctl(..., SIOCALIFADDR, ...) or into whatever *it* uses, it seems doable.
I'll see if I can figure out how to create an AF_LINK socket from within agr(4), but it's been quite a long time since I've been in the device driver code. :-)
Thanks for your pointer!
