disable_dgaf=1 in hostapd.conf can now be used to disable downstream group-addressed forwarding (DGAF). In this configuration, a unique GTK (and IGTK) is provided to each STA in the BSS to make sure the keys do not match and no STA can forge group-addressed frames. An additional mechanism in the AP needs to be provided to handle some group-addressed frames, e.g., by converting DHCP packets to unicast IEEE 802.11 frames regardless of their destination IP address and by providing Proxy ARP functionality.
