Since you are a regular poster to the wireless lists and you also
submitted a bug report
(http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2214 ) for this
issue it does not seem as though you need help in sending this to the
appropriate people.

... as I mention above you already submitted a bug report for this issue
and we directed you to a patch that addresses this. You have not replied
to that suggestion with any testing, instead you posted this message on
lkml.

How about you test the patch we proposed and work with the developers
working on your bug report?
