Add a tracepoint to the TLS offload's fast path. This tracepoint can be used to track the decrypted and encrypted status of received records. Records decrypted by the device should have decrypted set to 1, records which have neither decrypted nor decrypted set are partially decrypted, require re-encryption and therefore are most expensive to deal with.
