This patch integrates tayga with netifd. Parametres are nearly same as
with the older scripts. Support for static mapping of IPv4<=>IPv6 addresses
is missing. Example configuration:
config interface 'nat64'
option proto 'tayga'
option prefix 64:ff9b::/96
option dynamic_pool 10.128.0.0/24
option ipv4_addr 10.128.0.1 #address of the TAYGA itself
option ipv6_addr 2001:470:5990::64
option ipaddr 192.168.1.1 #optional address of TUN interface
option ip6addr 2001:db8::1
