Subject: [PATCH] Fix build with musl libc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

musl libc defines its own struct ethhdr that conflicts with the kernel
define one. The kernel headers provide a way to suppress its struct
ethhdr. For that to work the libc headers must precede the kernel. Move
the kernel linux/if_tun.h include below libc net/ethernet.h. That fixes
the following build failure:
