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.

- Hold rtnl lock during MTU update via netlink
Signed-off-by: Sven Eckelmann <sven@narfation.org>
The automatic recalculation of the maximum allowed MTU is usually triggered
by code sections which are already rtnl lock protected by callers outside
of batman-adv. But when the fragmentation setting is changed via
batman-adv's own batadv genl family, then the rtnl lock is not yet taken.
But dev_set_mtu requires that the caller holds the rtnl lock because it
uses netdevice notifiers. And this code will then fail the check for this
lock:

Because batman-adv is built under backports, not a clean linux tree,
the CONFIG_CFG80211 does not exist. The evaluation of IS_ENABLED() in
batadv_is_cfg80211_netdev() will be false, causing the funtion to
always return false.
This means that the wifi_flags of an interface don't get set, causing
batadv_is_wifi_hardif() to always return false. As a result,
batadv_v_elp_get_throughput() never tries to get the station info from
cfg80211, resulting in the following warning:
batman_adv: bat0: WiFi driver or ethtool info does not provide
information about link speeds on interface phy1-mesh0,
therefore defaulting to hardcoded throughput values of 1.0 Mbps.
So replace CONFIG_CFG80211 with CPTCFG_CFG80211, which is the correct
macro to use under backports.

Eric Dumazet changed the mc_forwarding in commit 145c7a793838 ("ipv6: make

This patch was then ported to various stable kernels.
This code change caused a FTBFS when in batman-adv when
CONFIG_BATMAN_ADV_MCAST was activated. To work around this problem, provide
a version for kernels with __s32 mc_forwarding and a version for kernel
with atomic_t mc_forwarding.

Commit 97d35a552ec5b6ddf7923dd2f9a8eb973526acea of musl introduced the
macros __LITTLE_ENDIAN and __BIG_ENDIAN in alltypes.h. These are pulled
into the compilation of batman-adv. This has the side effect that the
function is_multicast_ether_addr of etherdevice.h in Linux kernel is
compiled as the big endian version and so fails to work properly on
little endian devices.
This commits prevents pulling in header files of musl libc similar to

The batman-adv netlink messages often contain the interface index and
interface name in the same message. This makes it easy for the receiver to
operate on the incoming data when it either needs to print something or
needs to operate on the interface index.
But one of the attributes was missing for:
* neighbor table dumps
* originator table dumps
* gateway list dumps
* query of hardif information
* query of vid information
The userspace therefore had to implement special workarounds using
SIOCGIFNAME or SIOCGIFINDEX depending on what was actually provided.
Providing both information simplifies the userspace code massively without
adding a lot of extra overhead in the kernel portion.
