+Subject: [PATCH] rtlwifi: implement set_tim by update beacon content
+
+Once beacon content is changed, we update the content to wifi card by
+send_beacon_frame(). Then, STA with PS can wake up properly to receive its
+packets.
+
+Since we update beacon content to PCI wifi devices every beacon interval,
+the only one usb device, 8192CU, needs to update beacon content when
+mac80211 calling set_tim.
