RX_FORM_DEST_ERR is the RX Format and Destination 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_FCS_HEC_ERR ,
RX_FIFO_UR_ERR, RX_FIFO_OF_ERR, RX_MIN_ERR or RX_MAX_ERR counters, and
• In GFP mode, an error is found in the Type, DP, SP or Spare fields and checking of the corresponding
field is enabled.
• In LAPS mode, an error is found in the Address, Control or SAPI fields and checking of the
corresponding field is enabled.

RX_SYNC_ERR is the RX Out of Sync 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 only used in
GFP mode and is incremented each time the GFP synchronization state machine transitions from the Sync
state to the Hunt state.
