This seems to be a misrepresentation of the situation. The issues raised by
you were acknowledged as being valid, however they were not deemed important
enough to stop inclusion in wireless-next and net-next.

However, it is good to see that you have put effort in providing a patch series
for these issues.

Now, since I believe that it is better to work with people, rather than against
them, would it be possible to post this patch series somewhere as a set of 
separate patches, so that they can be reviewed as such?
