dnsmasq offers to group DHCP options and their values by a network-id
and to send options only to hosts which have been tagged with that

uci acceps the mac classifier, but only for a single MAC
config mac 'opnvpn'
        option mac  '00:FF:*:*:*:*'
        option networkid   'opnvpn'
        list   dhcp_option '3'

this patch allows a list of macs to be assigned to a network-id
config mac 'opnvpn'
	list   mac  '00:00:00:00:00:AA'
	list   mac  '00:00:00:00:00:BB'
	list   mac  '00:00:00:00:00:CC'
        option networkid   'opnvpn'
        list   dhcp_option '3'
