| All errors which is not matched others |
| XfrmInBufferError: |
| No buffer is left |
| XfrmInHdrError: |
| Header error |
| XfrmInNoStates: |

| 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 |
