ifOutErrors

This counter reports the number of bad TX frames terminated due to errors during transmission. The termination criteria include:
  • Assertion of tx_axis_mac_tuser.
  • Non-streaming TX data.
  • Dropped tx_axis_mac_tvalid before end of frame (Cut-Through mode only).
  • Frames discarded due to TX FIFO overflow in Store-Forward mode.

This counter does not increment for frames that are silently dropped due to non-compliant tx_axis_mac_tlast, or when tx_axis_mac_tuser is asserted during the first cycle of the frame. These conditions result in the frame being discarded without an error indication or a statistic update.
