+Subject: [PATCH] iptunnel.c: do not include netinet/ip.h
+
+This fixes a struct redefinition problem like this one:
+
+================================
+In file included from /usr/include/linux/if_tunnel.h:6:0,
+                 from iptunnel.c:34:
+/usr/include/linux/ip.h:85:8: error: redefinition of 'struct iphdr'
+ struct iphdr {
+        ^
+In file included from iptunnel.c:29:0:
+/usr/include/netinet/ip.h:45:8: note: originally defined here
+ struct iphdr
+        ^
+================================
+
+iptunnel.c includes netinet/ip.h which contains a definition of the
+iphdr struct.
+
+iptunnel.c also includes linux/if_tunnel.h which includes linux/ip.h
+which contains a definition of the iphdr struct.
+
+So, both netinet/ip.h and linux/ip.h define the iphdr struct, and both
+of them have been included directly or indirectly by iptunnel.c. Because
+of that the compilation fails due to a struct redefinition.
+
+The problem can be solved by just not including netinet/ip.h.
+
+However, some Linux headers included in certain toolchains may not have
+an updated linux/if_tunnel.h which includes linux/ip.h, so we need to
+include it unconditionally otherwise linux/if_tunnel.h will use the
+struct iphdr before being defined and the compilation will also fail in
+this way:
+
+================================
+In file included from iptunnel.c:33:0:
+/usr/include/linux/if_tunnel.h:37:16: error: field 'iph' has incomplete type
+  struct iphdr  iph;
+                  ^
+================================
