Hello, If you are talking about whether the zd1211 driver can buffer mcast/bcast frames in software, it seems to me that the answer is negative, since there is no call for ieee80211_get_buffered_bc() in the zd1211rw driver code and also there is no handling of IEEE80211_TX_CTL_SEND_AFTER_DTIM or IEEE80211_HW_HOST_BROADCAST_PS_BUFFERING in the zd1211rw driver code. This what made me add the NL80211_ATTR_WIPHY_AP_PS_CHALLENGED attribute and prepare this patch.
