3.5.7.17 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Sujith Manoharan <c_manoha@xxxxxxxxxxxxxxxx>
commit fcb9a3de1e72cb271343aa9484a20c066b6c4eee upstream.
This flag is used for indicating channel interference and
we currently do nothing with it, so remove it.
