+Subject: [PATCH] Fix build with uClibc-ng
+
+Add a local definition for IPPROTO_MH to fix build with uClibc-ng. As of
+version 1.0.25, the uClibc-ng netinet/in.h header does not provide this
+definition. The kernel provided definition is masked by libc-compat.h. Add
+this local fix until uClibc-ng syncs netinet/in.h with glibc.
+
+This partially reverts upstream commit a9ae195a2169 (xfrm: get #define's from
+linux includes)
