Allowing the (kernel) packet priority to be set through UCI.
This makes it straightforward to set some VLAN priority for DHCP
requests through a simple egress qos map. (Avoiding the need for
firewall matching and marking through iptables, which prevents using
flow offloading).
(Such priority tag is a hard requirement for some ISPs, such as Orange
in France).

odhcp6c logs messages related to its activity when invoked with -v, but
there is no way to configure this from within OpenWrt. This adds a UCI
option to turn on odhcp6c logging, disabled by default. To enable, set,
for example, network.wan6.verbose = 1.

dhcpv6.script contained support for disabling prefix delegation of 464XLAT
sub-interface, but netifd protocol handler was missing the required
export to disable this. Add missing export, akin to DS-Lite and MAP.

Placeholder DHCP user scripts were added recently.
These files make package-based installations of such scripts more difficult.
Pull user callbacks from directories instead to allow packages and users to
install co-existing scripts more easily.

Document the existence of this feature. This allows the user to execute a script
at each DHCPv6 event. This is useful, for example, as an ad-hoc way to update a
DDNS entry when (and only when) required.

Apply IPv6/ND configuration before proto_send_update so that all config info
is available when netifd is handling the notify_proto ubus call.
In particular this fixes an issue when netifd is updating the downstream IPv6 mtu
as netifd was still using the not yet updated upstream IPv6 mtu to set the
downstream IPv6 mtu

Be compatible with ISPs which don't support the destination option header containing
the tunnel encapsulation limit as reported in FS#1501 for dynamic created ds-lite/map
interfaces.
Setting the uci parameter encaplimit_dslite/map to ignore; allows to disable the insertion
of the destination option header for the dynamic created ds-lite/map interface.
Otherwise the tunnel encapsulation limit value can be set to a value from 0 till 255
by setting the encaplimit_dslite/map uci parameter accordingly.

Extendprefix is typically used to extend an IPv6 RA prefix from a mobile
wan link to the LAN; such scenario requires correct RA prefix settings
like the on link flag not being set.
However some mobile manufacter set the RA prefix on link flag which breaks
basic IPv6 routing.
Work around this issue by filtering out the route being equal to the
extended prefix.

Add option keep_ra_dnslifetime which will preserve the received
lifetime for RDNSS and DNSSL RA records and not overwrite it
by the RA router lifetime as specified in RFC6106.

a default route by setting router lifetime to 0 in the RAs.

Some ISP seem to only do stateful DHCPv6 and not sending RAs.
This is technically broken because plain DHCPv6 doesn't carry routes.
We work around here by faking a default route to the DHCPv6 server
if we do not receive a useful RA from the ISP.
This workaround can be turned off with: option fakeroutes 0
