+XFRM proc - /proc/net/xfrm_* files
+==================================
+Masahide NAKAMURA <nakam@linux-ipv6.org>
+Transformation Statistics
+-------------------------
+xfrm_proc is a statistics shown factor dropped by transformation
+for developer.
+It is a counter designed from current transformation source code
+and defined like linux private MIB.
+Inbound statistics

+        No buffer is left
+XfrmInHdrError:
+        Header error
+XfrmInNoStates:
+        No state is found
+        i.e. Either inbound SPI, address, or IPsec protocol at SA is wrong
+XfrmInStateProtoError:
