Fixed Interfaces tab and staged updates.

Update to the latest kernel and drop two patches related to Omnia LEDs
as they were merged upstream.

This option of IPv6 Router Advertisements allows devices connected to
a IPv6-only network to discover IPv6 prefix of the NAT64 gateway.
Devices can use this information for instance to setup client translator
(CLAT) from IPv4 to IPv6 in 464XLAT (RFC 6877) scenario or to handle
IPv4 address literal on application level.

To enable PREF64 option, a new uci parameter ra_pref64 has to contain
the NAT64 prefix, including prefix length. Only lengths of 96, 64, 56,
48, 40 and 32 bits are supported. For example, to annonce the Well-Known
Prefix:

config dhcp 'lan'
        …
        option ra_pref64 '64:ff9b::/96'

For details see the included patch serie or the github repo:
https://github.com/turris-cz/easycwmp

On WAN side automatically request prefix delegation. On LAN side use
eui64 as static IPv6 identifier (::1 is an easy target) and assign also
fe80::1 to the interface as it is common IPv6 address for a default
gateway.
