config: add xfrm interface support scripts
This package adds scripts for xfrm interfaces support. Example configuration via /etc/config/network: config interface 'xfrm0' option proto 'xfrm' option mtu '1300' option zone 'VPN' option tunlink 'wan' option ifid 30 config interface 'xfrm0_static' option proto 'static' option ifname '@xfrm0' option ip6addr 'fe80::1/64' option ipaddr '10.0.0.1/30' Now set in strongswan IPsec policy: if_id_in = 30 if_id_out = 30 Signed-off-by: André Valentin <avalentin@marcant.net>
