8704d138df xfrm: simplify the check for necessary kernel support 
[ -d /sys/module/xfrm_interface ] is enough to check if
CONFIG_XFRM_INTERFACE support was enabled in kernel.

5d2b577a53 xfrm: support 'multicast' attribute on interfaces 
You shouldn't need the overhead of GRE just to add multicast
capability on a point-to-point interface (for instance, you might
want to run mDNS over IPsec transport connections, and Avahi
requires IFF_MULTICAST be set on interfaces, even point-to-point
ones).

Borrowed heavily from:

452d88e8f7 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
