Sorry, Baruch.  I missed two comments in the last reply.

Hi Shawn,

Please add netdev at vger.kernel.org to the Cc of all your fec driver patches.

I was aware of this after I sent out the patch set last night.
Can I just resend all the patches in v2 and get netdev at vger.kernel.org
included?

Again, how do you handle the dual MAC case?

For the platform data case, the following patch reads both mac
addresses.
