Default [Q] Multicast is waking device in large subnets

I'm experiencing bad battery times when connected through wifi on networks such as at my university, using network logger I found that this is due to multicast traffic which is waking up the device. I've read that the N4 also has had this issue but they can filter multicast from waking up the device when screen is off through the file:
`/system/etc/wifi/WCNSS_qcom_cfg.ini`

Does anyone know of anything comparable on the M7?

I'm running latest cyanogenmod 11M5.
