37.6.6.35 RFC – Receive Fragment Count Register
This register counts the number of received frames that passed address filtering, and
were less than minimum size (64B from <Destination Address> through <CRC>,
inclusively), but had a bad CRC (this is slightly different from the “RUC – Receive
Undersize Count Register” on page 1523). This register will only increment if receives
are enabled.

37.6.6.36 ROC – Receive Oversize Count Register
This register counts the number of received frames that passed address filtering, and
were greater than maximum size. Packets over 1522 bytes are oversized if
LongPacketEnable is clear (i.e. RCTL.LPE=0). If LongPacketEnable is set, then an
incoming, packet is considered oversized if it exceeds 16384 bytes. If receives are not
enabled, this register will not increment. These lengths are based on bytes in the
received packet from <Destination Address> through <CRC>, inclusively.
