The batadv_vlan proto doesn't need to do anything when it gets teared down.
But the scripts are still trying to call the teardown function of this
proto. This results in warnings like:
daemon.notice netifd: batmesh1 (18940): ./batadv_vlan.sh: eval: line 37: proto_batadv_vlan_teardown: not found
Just providing a stub function avoids this log spam.

The '-m' option to select the mesh interface or vlan interfaces was
replaced with device type specific subcommand prefixes:
* meshif <netdev>
* vlan <vdev>
* meshif <netdev> vid <vid>
* hardif <netdev>
This change should also be made in the proto script to allow batctl to drop
the support of '-m' completely in the future.

The ap_isolation setting only supports boolean values. So setting an empty
string as ap_isolation is not supported by batctl.

B.A.T.M.A.N. V support additional settings which are hardif specific. The
batadv_hardif proto has to expose them to allow automatic configuration.
The default configuration would be:
config interface 'bat0_hardif_eth0'
option proto 'batadv_hardif'
option master 'bat0'
option ifname 'eth0'
option mtu '1536'
option 'elp_interval' 500

option 'throughput_override' '0'

Although batman-adv config is cycled in config_foreach, changes

batman-adv allows to configure three different objects:
* batadv hardif
- network interface used by batadv meshif to transport the batman-adv
packets
- its master interface is set to the batadv meshif
* batadv (meshif/softif)
- virtual interface that emulates a normal 802.3 interface on top
- encapsulates traffic and forwards it via the batadv hardifs
* batadv vlan
- potential VLAN ID on top of batadv meshif
- allows filtering of traffic from specific VIDs
While batadv vlan objects were already represented as an own proto
"batadv_vlan", the batadv meshif could never be fully configured using
/etc/config/network. Instead, parts of its configuration were stored in
/etc/config/batman_adv and some in the interfaces with the "batadv" proto.
To increase the confusion, the "batadv" proto wasn't used to define the
batadv meshif but to identify batadv (slave) hardifs. The batman-adv
meshifs were also never created directly but only when a hardif was
configured. The actual modification of the configuration settings was then
applied using a hotplug script hack. The batadv meshif network interface
could therefore only be created when an hardif was available and not
manipulated with ifup/ifdown. Also `/etc/init.d/network reload` didn't
modify the batadv meshif interface configuration correctly.
The "batadv" is now renamed to "batadv_hardif" and a new "batadv" proto is
used to configure the main (meshif) network interface with all its
configuration.
A simple network configuration with WiFi & ethernet interfaces and static
IP on top of bat0 would look like:
# batadv meshif bat0
config interface 'bat0'
option proto 'batadv'
option routing_algo 'BATMAN_IV'
option aggregated_ogms 1
option ap_isolation 0
option bonding 0
option fragmentation 1
#option gw_bandwidth '10000/2000'
option gw_mode 'off'
#option gw_sel_class 20
option log_level 0
option orig_interval 1000
option bridge_loop_avoidance 1
option distributed_arp_table 1
option multicast_mode 1
option network_coding 0
option hop_penalty 30
option isolation_mark '0x00000000/0x00000000'
# add *single* wifi-iface with network bat0_hardif_wlan as hardif to bat0
config interface 'bat0_hardif_wlan'
option mtu '1536'
option proto 'batadv_hardif'
option master 'bat0'
# option ifname is filled out by the wifi-iface
# add eth0 as hardif to bat0
config interface 'bat0_hardif_eth0'
option proto 'batadv_hardif'
option master 'bat0'
option ifname 'eth0'
option mtu '1536'
# configure IP on bat0
config interface 'bat0_lan'
option ifname 'bat0'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'

hop_penalty is the last remaining setting which is directly writing to
sysfs instead of using a implementation (sysfs vs. netlink) abstraction
layer. batctl now provides a wrapper function that allows the script to
directly use it to take care of communicating with the driver.

The batctl tool should be used for modifying settings in the batman-adv
driver to keep the scripts consistent and allow to use the correct way of
communicating with the kernel (sysfs vs. netlink).
The gw_mode, gw_bandwidth and gw_sel_class options are all handled by
the same gw_mode command in batctl and thus have to be combined depending
on the "gw_mode" value.

The batctl binary is currently optional for batman-adv installations. But
new configuration settings will only be exposed via generic netlink. The
batctl tool will therefore be required to modify them.
batctl must therefore no longer depend on batman-adv but batman-adv must
depend on batctl. Some already implemented settings are already moved to
batctl.

Users may want to know what options can be specified and in which form they
have to specified. A commented out list of settings is helpful here while

routing algorithm via the option routing_algo. This allows to chose between

is added to an already existing batman-adv device.
