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

Fix broken DHCPv6 servers which provide the server unicast option but
do not reply on DHCPv6 renew messages directed to the IPv6 address
contained in the server unicast option whihc results in broken IPv6
connectivity.

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.

Support configuration in the form...
list ip6prefix 2001:db8:1234::/64
list ip6prefix 2001:db8:5678::/64
... to allow specifying multiple additional IPv6 prefixes.
Implements feature request FS#1361.

Don't append an empty sendopts value as odhcp6c bails out
immediately on an empty -x option triggering an infinite start
loop of odhcp6c
Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
Commit a26045049b added support for sendopts as a string; since multiple
sendopts values can be specified it makes more sense to model it as a
list of strings.

By default odhcp6c asks for a default list of options; the config option
defaultreqopts allows to tweak this behavior.
When set to 0 odhcp6c will not ask for any options except for the options
specified in the reqopts config option.

Add sendopts config support allowing to add options in sent DHCPv6 packets.
Options can be configured as follows :
uci set network.wan6.sendopts="sntpservers:3001:3001::1,3001:3001::2 11:00000000000000000000006674692F 0x3e8:ABCDEF"

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.
This allows to accept RDNNS records from RAs that don't announce
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
