Then issue a command. CRC is calculated from this MAC and appropriate bit written to the HASH register. - In loopback rx_clk is not looped back. Possible CRC error. Consider if usage of additional logic is necessery (FIFO for looping the data). - When sending frames bigger than MaxFL, MaxFL is sent, BD marked as finished, TxB_IRQ interrupt is set and MTxErr is set for a short period. Fix MTxErr or prevent sending too big frames or set TxE_IRQ instead.
