[PATCH V4] multiple_bssid: add support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add support for multiple bssid. In order to be able to do EMA HW offloading
inside the kernel, we need to send the multiple bssid elemets inside a
dedicated nl80211 arreibute.

Changes in V4
* make the patch work with the latest mac80211 series
