Ethernet Controller
Register 8: Ethernet MAC Individual Address 1 (MACIA1), offset 0x018
This register enables software to program the last two bytes of the hardware MAC address of the
Network Interface Card (NIC). (The first four bytes are in MACIA0). The 6-byte IAR is compared
against the incoming Destination Address fields to determine whether the frame should be received.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
MAC Address Octet 6
The MACOCT6 bits represent the sixth octet of the MAC address used
to uniquely identify each Ethernet Controller.
MAC Address Octet 5
The MACOCT5 bits represent the fifth octet of the MAC address used to
uniquely identify each Ethernet Controller.
