For example, the destination MAC address includes the following six octets
AC-DE-48-00-00-80, the first octet transmitted (octet 0 of the MAC address described
in 802.3) is AC and the last octet transmitted (octet 7 of the MAC address) is 80. The
first bit transmitted is the low-order bit of AC, a zero. The last bit transmitted is the
high order bit of 80, a one.
frame are transferred over the Tx datapath. As
0xAC is driven on DA5[47:40] and 0x80 is driven on DA0[7:0].
The Rx MAC receives Ethernet frames from the PHY and forwards the payload with
relevant header bytes to the client after performing some MAC functions on header
bytes. Some of the header bytes are optionally stripped from the frame before
forwarding.
