Figure 3–20
Figure 3–20. RX MAC FIFO Interface
The Rx FIFO interface does not include a backpressure signal to stop the flow of data
from the Rx MAC. The sink must be able to consume data continuously from the
MAC.

64-bit client or source data for transmission.
When asserted indicates that the rest of the signals in the interface are valid.
Asserted for one cycle to indicate the start of a packet.
Asserted for one cycle to indicate the end of a packet.

Indicates the current packet has an error. Asserted in conjunction with the
user_rx_eop signal.
Indicates that the received frame is a VLAN tagged frame.
Indicates that the received frame is a stacked VLAN tagged frame.
