you are right, sorry.
I do a lot of tests  and sometime it seems  wireguard is in  a "strange"
state, I'm trying to reproduce.

A question :
When I've the dmesg, "could not create ipv4 socket", i cannot rmmod
wireguard from kernel.
I'm trying
ip link del dev wg0  ,
rmmod wireguard
there's no wireguard interface, however, i cannot remove wireguard module,
system tells module is used.

When wireguard works well, i can remove module without problem.

Regards,
Nicolas
