Jani, Daniel, could I merge the 5 patches already after CI respond?
I rebased and retest here on CNL.... But I'd like to start merging so
we unblock CFL as well, maybe on top of this CNP before CNL...
Jani, also I believe you would be the best reviewer for this 6th patch
here, could you please consider taking a look?
Thanks,
Rodrigo.
