bridge: Allow setting multicast_router option
The multicast_router option of a bridge allows to control the forwarding
behaviour of multicast packets independant of the listener state:
* 0: Only forward if specific listener is present
* 1 (default): Forward if specific listener or a multicast router
was detected (currently only learned via query messages, no MRD
support yet)
* 2: Always forward any multicast traffic on this port
Since MRD is not mandated you might end up with silent multicast routers
(e.g. if your link has more than one multicast router; only one can
become the selected, "noisy" querier). Here you might need a manual
configuration option like the "multicast_router" option.
Other scenarios where this can be useful are for instance:
* Segmentation of IGMP/MLD domains together with ebtables
* Dedicated bridge port for monitoring/debugging purposes

bridge: Fix multicast_to_unicast feature by hairpin+isolate
All IGMP and MLD versions suffer from a specific limitation (from a
snooping switch perspective): Report suppression.
Once a listener hears an IGMPv2/3 or MLDv1 report for the same group
itself participates in then it might (if this listener is an IGMPv3 or
MLDv2 listener) or will (if this is an IGMPv1/2 or MLDv1 listener)
refrain from sending its own report.
Therefore we might currently miss such surpressing listeners as they
won't receive the multicast packet with the mangled, unicasted
destination.
Fixing this by first isolating the STAs and giving the bridge more
control over traffic forwarding. E.g. refraining to forward listener
reports to other STAs.
For broadcast and unicast traffic to an STA on the same AP, the hairpin
feature of the bridge will reflect such traffic back to the AP
interface. However, if the AP interface is actually configured to
isolate STAs, then hairpin is kept disabled.

Enable callers to pass the source IP of an IPv4 route when using
proto_add_ipv4_route(). This is useful with for example DHCP in a multihomed
scenario, as it provides an easy way to match default routes with the correct IP
address. One use case for this are applications that monitor the state of the
WAN port, and the WAN port is assigned multiple addresses.

netifd v2: Fix source routing for IPv4
According to the OpenWRT Network documentation for route, the 'source' option is
"The preferred source address when sending to destinations covered by the
target". However, netifd currently stores this value in RTA_SRC on
NEWROUTE/DELROUTE.
RTA_SRC is not used by kernel when handling NEWROUTE nor DELROUTE for IPv4
routes. When adding a new IPv4 route, the source is stored in RTA_PREFSRC and
the option works as specified in documentation. For IPv6, the address is still
stored in RTA_SRC as to not break source-destination routing for IPv6.
v2: Limit patch to IPv4, to prevent breaking IPv6 configurations (thanks Steven
Barth)

netifd: Read current link state when processing netlink event
Netifd commit
b2dcb02570939d98b92c7c55db1c328693a5d52a introduces
a race condition resulting into infinite toggling interfaces
(eg static interfaces with linksensing enabled, vlan interfaces
with proto none (#18106)) when linksensing is enabled resulting into
a crash.
As netlink event messages will be queued on the netlink event socket
the included lower up interface flag will not always represent the
current link state when netifd processes the netlink messages;
by reading the current link state when a netlink event message is
parsed the correct info is passed to the device layer.
This will avoid continuous interface toggling (down/up) triggered
by link state changes based on outdated netlink interface info.
