Hello,

it's me again with my super ancient kernel *sigh*

I'm getting these errors with the 0.0.20180925 snapshot :

I understand if it's just no possible anymore to support such ancient
software. Instead of collecting dust it serves as a nice wireguard
endpoint :)

Wireguard has been amazing so far, thanks for such great software.
