This patch is wrong, in many different acpects. Leaving the submission
style, and no in-tree consumer aside, adding ndos for this thing is
unacceptable. It should be handled as a part of switchdev attrs.
Also, the solution should not be bonding-centric.

I have a patchset in my queue which does this correctly, for bond and team
using switchdev attr and with actual in-tree consumer, mlxsw driver.
I plan to send that soon after net-next opens.
