thanks Mario, do you also plan to open upstream bugs for the userland changes required?

I've adjusted the description for the alternate approach in doing this entirely in the kernel. I've submitted a patch to LKML for this here.

https://patchwork.kernel.org/patch/9148319/

Upstream hasn't flat out rejected this patch, but they also haven't been openly accepting the patch.

As this is for enabling docks to properly work (as intended by OEM) in Ubuntu can this be carried as Ubuntu SAUCE? The latest version of the patch and discussion about it is available here:
http://patchwork.ozlabs.org/patch/631759/

It will only affect docks that have a special realtek chip with a special bit set indicating that they are docks and should take the firmware mac address.

Thanks,

David Miller applied this. Could it please be pulled into Ubuntu as sauce now?

This is upstream now too.

Merged for 4.8

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Looks good to me:
