If we set the option "local_source" in the globals mwan3 section to "none",
traffic generated by the router it self will always use the default route from
the wan interface with the lowest metric. If this interface is down
the router traffic still uses the connection with the lowest metric but
this is disconnected. Load balancing and failover from the lan site is
still possible. Only router generated traffic is not load balanced and
could not use failover.
To solve this issue with router initiated traffic add the additional
option "online_metric" to the mwan3 interface section.
If the interface is connected then this lower "online metric" is set in the
default routing table.
With this change we have at least a failover with router initiated
traffic.

During runntime of mwan3 we could add dynamicly networks to this ipset
which would then treated as connected networks by mwan3.
This is also usefull for ipsec.

With the list param "rt_table_lookup" in the mwan3 section globals,
it is now possible to add a additional routing table numbers which would get
also parsed and will be added to the connected network.
So mwan3 will treat them as they are directly connected to this device.
This could be usefull if we use ipsec.

- The original copy process is to delete all routing tables first,
then add new routing table. This process is too slow and very dirty.
- We use grep to identify the changes and apply them.
- ignore ipv6 unreachable routes
- update version number

If an interface is not tracked by mwan3 or enabled and this interface is
setup by netifd, then the connected ipset is not update by mwan3.
To fix this also call connected ipset update code even if the interface
is not tracked or enabled by mwan3.

The normal situation should be to use ping without quality_check.
If quality_check option is not set in the default option then ping
quality_check is not performed during tracking. This is and should

Considering that ipv6 NPT/NAT/NETMAP is done manually by user,
mwan3 can balance ipv6 interfaces as it does with ipv4.
Interface wan2 was renamed to wanb as wan2, wan3, ... will eventually
colide with OpenWrt with default wan6 interface when more than 6
interfaces are in use.
New interfaces, members for wan6 and wanb6 where created, both disabled
by default. Policies where adapted as well.
The option "family" is set respectively in each interface. When missing,
mwan3 assumes ipv4, that will fail when interface is IPv6 only.

The IPsec ip route table has the default number 220.
If mwan3 has more then 7 bits set (124 interfaces) then if mwan3 down is
executed the table is also cleared. To solve this set default max 7
bits in the mmx_mask for mwan3.

We need always three of the firewall mask value for
* default routing table
* blackhole
* unreachable
the other will be used for the interfaces.
* If we have set the mmx_mask to max 0xFF00 (8 bit set) we could use max 252
interfaces.
* If we have set the mmx_mask to min 0x0E00 (3 bit set) we could use max 4
interfaces.
Only the ones are counting from the firewall mask value.
Minimal three firewall mask bit vaules must be set.
Maximal eight firewall mask bit vaules could be set.
Table overview mmx_mask value bits vs. max interfaces
mmx_mask value bits set 1 -> not usefull
mmx_mask value bits set 2 -> not usefull
mmx_mask value bits set 3 -> 4 Interfaces (mask example 0x0E)
mmx_mask value bits set 4 -> 12 Interfaces
mmx_mask value bits set 5 -> 28 Interfaces
mmx_mask value bits set 6 -> 60 Interfaces
mmx_mask value bits set 7 -> 124 Interfaces
mmx_mask value bits set 8 -> 252 Interfaces (mask example 0xFF)

Interfaces of some PtP protocols do not have a real gateway. In that
case ubus may fill them with '0.0.0.0' or even leave it blank. This
will cause error when adding new routing rule.
