Currently when assigning IPv6 addresses with large prefixes to a wireguard
interface, like
config interface 'wg'
option proto 'wireguard'
list addresses 'fd::/48'
and having, say, a LAN interface such as
config interface 'lan'
option proto 'static'
option ip6assign '60'
as is default the interface does not automatically receive the wg
interface's prefix.
For this to happen the proto needs to use proto_add_ipv6_prefix to register
the fact that a prefix is available for assignment which is simple enough.
Note that the addresses configured here usually include a non-zero host
part but currently netifd handles this poorly when more than one interface
should receive a sub-prefix.
The required fix can be found in "[PATCH netifd] interface-ip: Normalise
prefix address using netmask before using it" (Message-Id:
<20201125173536.1175-1-d...@darkboxed.org>)
