How to disable beacon filtering in iwlwifi in 3.13 and 3.14

Hi,

I need to disable a feature on 3.13 and 3.14. But I don't have any
patch upstream that I can point to as the patch that needs to be
backported.
We have a feature that is buggy in 3.13 and 3.14. We refactored (and
fixed) this feature in 3.15 but the refactor is really not stable
material, so basically, I can't backport the fix to 3.13 / 3.14. A
user reported that disabling the feature solved (part of) his issues:
https://bugzilla.kernel.org/show_bug.cgi?id=72601.
OTOH, I don't have any patch in linux.git that could be backported to
do what I want in 3.13 / 3.14 - i.e. disable the feature.
What is the right process here? I understand that this isn't covered
by the "stable rules". So what should I do here?

FYI: this is the patch:

    iwlwifi: mvm: disable beacon filtering

    This feature has been causing trouble - disable it for now.
    Fixes are available, but they are too big to be backported.
