I do not like setting this option to one by default. The idea of
flowlabel_consistency above was to be sure that all labels given by the
host are in the control of the flow label manager.

By enabling auto_flowlabels, we can have conflict between the flow label
manager policy, and a randomly generated label.

And I do not have a strong opinion on it, but perhaps should
auto_flowlabels depends of a disabled flowlabel_consistency, to have a
coherent behaviour for users.

Regards,

Florent.
