    3936.	[func]		Added authoritative support for the EDNS Client
    			Subnet (ECS) option.
    
    			ACLs can now include "ecs" elements which specify
    			an address or network prefix; if an ECS option is
    			included in a DNS query, then the address encoded
    			in the option will be matched against "ecs" ACL
    			elements.
    
    			Also, if an ECS address is included in a query,
    			then it will be used instead of the client source
    			address when matching "geoip" ACL elements.  This
    			behavior can be overridden with "geoip-use-ecs no;".
    
    			When "ecs" or "geoip" ACL elements are used to
    			select a view for a query, the response will include
    			an ECS option to indicate which client network the
    			answer is valid for.
    
    			(Thanks to Vincent Bernat.) [RT #36781]
