TX_ER_ERR is the TX_ER 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 frames where TX_ER was detected active while the frame was being
received but did not cause a FIFO error.

TX_FIFO_OF_ERR is the TX_FIFO Overflow 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 each time there is a FIFO overflow and hence a frame is discarded.
