+Subject: [PATCH] sysdep.c: don't include <linux/if_tun.h> on Linux
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Including <linux/if_tun.h> in sysdep.c is not necessary since sysdep.h
+already includes <netinet/if_ether.h>. And this is actually
+potentially harmful since both files redefine the same 'struct
+ethhdr', causing the following build failure with the musl C library:
+
+In file included from sysdep.h:28:0,
+                 from sysdep.c:71:
+.../buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/netinet/if_ether.h:96:8: error: redefinition of ‘struct ethhdr’
+ struct ethhdr {
+        ^
+In file included from .../buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/linux/if_tun.h:20:0,
+                 from sysdep.c:62:
+.../buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/linux/if_ether.h:138:8: note: originally defined here
+ struct ethhdr {
