rpt_rx_frame_length

The statistic rpt_rx_frame_length reports the length of each RX frame received at the RX AXI ST Interface. Frame length is inclusive of the headers (6 octets of destination address, 6 octets of source address, the optional 4 octets of VLAN tag, and 2 octets of ETHERTYPE/LEN), payload, and 4 octets of FCS. This statistic updates at the same clock cycle as the end of frame. Refer to the figures, where statistic rpt_rx_frame_length is illustrated.

The RX frames that are filtered away due to broadcast, unicast, and multicast filtering do not appear at the RX AXI ST. Hence, this statistic does not report the frame length for the dropped RX frames.
