SS_SnifferIndication (5Eh)

This command is sent by the ST7580 after a reception of a power line frame that couldn't be

decrypted through the key value stored in the MIB object SS_Key 02h (Section 4.2.3) and it

exports the SS_Sniffer indication service (Section 2.4). The command notification occurs if

the modem is set for receiving SS frames at MIB object Modem Config 00h (Section 4.2.1),

as in the diagram flow in Figure 5.

The IndicationData fields are the same as for PHY_DataIndication (Table 39). The payload

field won't present the wrong CRC bytes.
