The total number of frames received on a port that were dropped (zero port_mask) due to a secure violation (the source address is owned by a different receive port).
- was any data or MAC control frame which matched a unicast, broadcast or multicast address, or matched due to promiscuous mode, and
- Any length (including less than 64 bytes and greater than RX_MAXLEN bytes)
- had no CRC error, alignment error, or code error, and
- the source address is an entry in the table with the SECURE bit set and a port number for a different receive port.
