cnt_rx_frame_undersized
The statistic cnt_rx_frame_length reports the number of RX frames with
payload size < 46 for the non-VLAN tagged frames, or < 42 for VLAN tagged frames.
This statistic updates at a clock cycle after the end of the frame. Figure 1 shows the cnt_rx_frame_undersized statistic updates relative to the
RX frames at the AXI ST interface.
When this statistic register increments, the RX statistic registers,
cnt_rx_mismatched_length and
cnt_rx_frame_error_fcs remain unchanged.
