[PATCH] iw: add support for setting the multiple bssid transmitting flag

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

 



When we want to use multiple bssid, we need to indicate that the primary
AP is transmitting at time of creation. This patch adds a new parameter
to achieve this.

Hi Johannes,
the patch requires the new nl80211.h from after applying the multiple bssid
kernel series.
