RX_MII_FRAMES_XMIT_OK is the RX MII Frames Transmitted OK counter. It is non-resetable except that a hard or soft reset will clear it. After reaching its max value the counter starts over from zero again. This counter is incremented by each complete frame that is transmitted on the MII interface without RX_ER being asserted. That is, it is incremented by each frame that did not increment any one of the error counters.

RX_FCS_HEC_ERR is the RX FCS and HEC Error counter. It is non-resetable except that a hard or soft reset will clear it. After reaching its max value the counter starts over from zero again.

This counter is incremented by each frame that did not increment any of the RX_FIFO_UR_ERR,

RX_FIFO_OF_ERR, RX_MIN_ERR or RX_MAX_ERR counters, but was received with an FCS or HEC error (and checking was enabled) or contained an unrecognized LAPS control flag.
