Byte	Data Field
NetFn	30h
CMD	93h
1: 3	Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h.
4	Sub command, sub command=5eh
5	Reserved extended field. Set it to 0.
6	Query the type of the network port. 0: Physical port
7: 8	Query parameter 0000h: Obtain the number of network ports. Other values: Obtain information about a specified network port. The value indicates the index number of the business port.
