+Subject: [PATCH] libxt_TCPMSS.c: unbreak build without ipv6 after ea2a02f7
+
+ea2a02f7 (libxt_TCPMSS: use guided option parser) added an netinet/ip6.h
+include, which is not available on systems without ipv6.
+
+The ip.h / ipv6.h includes are only used to know the size of struct
+iphdr / ip6_hdr, so simply hardcode those instead.
