I have acked your patch but haven't had time to compile and test it.
Will do this in due course and integrate it into the test tree. 

With regard to the error message, this says that the feature with index 0
could not be activated. According to table 6.4 in RFC 4340 this is a bug
because it tries to activate a reserved feature.

Will do in-depth testing later on today.
