What about EUI-64 MAC addresses? Do we need/want to care about them?
Yes why such a restrictive check?
Why not just "if (addr_size < ETH_ALEN)" above?
I can't see why it should be an error to provide a buffer that is
larger than absolutely necessary.

Application should request valid size, isn't it? I.e. 6 or 8. What is
the use to request more then can be returned?
Maxim.
I did linux-generic implementation for hw which I have. EUI-64 can be added
with other
patch which we should test first. Can EUI-64 be set up with the same ioctl
or something else
is needed? I need to take a look at it separately.
