Does KSZ8995 need a unique MAC address with EEPROM?
KSZ8995 does not require a unique MAC address with EEPROM, either to be used for an unmanaged or managed switch. Registers 68h to 6Dh are used for pause frame only. The data frame's MAC address comes from either a processor by software or the Ethernet controller's EEPROM. The Ethernet switches just switch these data packets with their SA and DA MAC address only.
