How can I get Unique ID in DM8168?

Usually, the Mac ID can be used as the unique ID.

hi eason,

MAC ID can be changed in software. I wan get serial id that unique and can't be changed.
thanks,

There is unique Mac ID flashed into the chip. Just read the registers, dont use the mac id from ifconfig cmd.
Pls search MAC_ID0_LO in TRM.
DM8168 has to EMAC module thus there are 2 Mac ID.

BR,
Eason
