-Transformation Statistics
--------------------------
-
-The xfrm_proc code is a set of statistics showing numbers of packets
-dropped by the transformation code and why.  These counters are defined
-as part of the linux private MIB.  These counters can be viewed in
-/proc/net/xfrm_stat.
-
-
-Inbound errors
-~~~~~~~~~~~~~~
-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
-XfrmAcquireError:
-	State hasn't been fully acquired before use
-XfrmFwdHdrError:
-	Forward routing of a packet is not allowed
-
-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:
-	Sequence error
-	i.e. Sequence number overflow
-XfrmOutStateExpired:
-	State is expired
-XfrmOutPolBlock:
-	Policy discards
-XfrmOutPolDead:
-	Policy is dead
-XfrmOutPolError:
-	Policy error
-XfrmOutStateInvalid:
