API level 30(Android 11) will be mandatory starting November 2021 for apps on the PlayStore but seems to break golangs interface address discovery: golang/go#40569

This seems to be an intended privacy related change which directly affects how golangs stdlib retrieves addresses for an interface:

• NetworkInterface.getHardwareAddress() returns null for every interface.
• Apps cannot use the bind() function on NETLINK_ROUTE sockets.
• The ip command does not return information about interfaces.
• Apps cannot send RTM_GETLINK messages.
