+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
+~~~~~~~~~~~~~~~~~~
+XfrmInError:
+ All errors which is not matched others
+XfrmInBufferError:
+ 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:
+ Transformation protocol specific error
+ e.g. SA key is wrong
+XfrmInStateModeError:
+ Transformation mode specific error
+XfrmInStateSeqError:
+ Sequence error
+ i.e. Sequence number is out of window
+XfrmInStateExpired:
+ State is expired
+XfrmInStateMismatch:
+ State has mismatch option
+ e.g. UDP encapsulation type is mismatch
+XfrmInStateInvalid:
+ State is invalid
+XfrmInTmplMismatch:
+ No matching template for states
+ e.g. Inbound SAs are correct but SP rule is wrong
+XfrmInNoPols:
+ No policy is found for states
+ e.g. Inbound SAs are correct but no SP is found
+XfrmInPolBlock:
+ Policy discards
+XfrmInPolError:
+ Policy error
+
+Outbound errors
+~~~~~~~~~~~~~~~
+XfrmOutError:
+ All errors which is not matched others
+XfrmOutBundleGenError:
+ Bundle generation error
+XfrmOutBundleCheckError:
+ Bundle check error
+XfrmOutNoStates:
+ No state is found
+XfrmOutStateProtoError:
+ Transformation protocol specific error
+XfrmOutStateModeError:
+ Transformation mode specific error
+XfrmOutStateSeqError:

+ i.e. Sequence number overflow
+XfrmOutStateExpired:
+ State is expired
