That would be the worst option. Then the kernel shows bogus values and no one 
is helped.


And how should I prove it to you? Is that enough?

    $ lsmod|grep '^batman_adv'
    batman_adv            266240  0
    $ sudo batctl -v
    batctl debian-2022.3-2 [batman-adv: module not loaded]
    $ sudo batctl if add enp70s0
    Error - batman-adv module has not been loaded
    $ sudo ip link show dev bat0       
    8: bat0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
        link/ether 7a:8b:21:b7:13:b8 brd ff:ff:ff:ff:ff:ff
    $ sudo ip link set master bat0 dev enp70s0
    $ sudo ip link set up dev bat0
    $ sudo batctl n                         
    Missing attributes from kernel
    $ sudo batctl o
    Missing attributes from kernel


Expected was following output:

    $ sudo batctl -v
    batctl debian-2022.3-2 [batman-adv: 2022.3]
    $ sudo batctl if add enp70s0
    $ sudo ip link show dev bat0
    $ sudo ip link set up dev bat0
    $ sudo batctl n

    IF             Neighbor              last-seen

    $ sudo batctl o
