IEEE Std 802.11-2012, 10.19 (Public Action frame addressing) specifies that the wildcard BSSID value is used in Public Action frames that are transmitted to a STA that is not a member of the same BSS. hostapd used to use the actual BSSID value for all such frames regardless of whether the destination STA is a member of the BSS. Fix this by using the wildcard BSSID in cases the destination STA is not a member of the BSS. Leave group addressed case as-is (i.e., the actual BSSID), since both values are accepted. No such frames are currently used, though. This version is still using the AP BSSID value in the Address 3 field for GAS response frames when replying to a GAS request with AP BSSID instead of Wildcard BSSID. This is left as a workaround to avoid interoperability issues with deployed STA implementations that are still using the non-compliant address and that might be unable to process the standard compliant case.
