The statistics for the transmitted frame are contained within the tx_statistic_vector. The vector is driven synchronously by the transmitter clock, gtx_clk, following frame transmission. The bit field definition for the vector is defined in Table 5-4.

All bit fields, with the exception of byte valid, are valid only when

tx_statistic_valid is asserted (Figure 5-11). Byte valid is significant on every gtx_clk cycle.

Caution! The statistic vectors in this release have been made compatible with the Tri-Mode

Ethernet MAC core. They are not backwards compatible with previous versions of the 1-Gigabit

Ethernet MAC core (see Table 5-5for Transmitter Statistic Vector conversion details).
