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. Reported-by: Maciej S.
