Hi Dipendra,

Thanks for the updates,

I agree that this addresses Maxime's changes.  I've CCed him here, please
consider CCing people who comment on earlier revisions of patches.

My only nit about this patch is that, as per mo comment on [1], I think the
prefix in the subject should be 'octeontx2-pf: '.
