All ports
The total number of frames received on a port such that the destination address was not equal to the source address and the packet was not destined to the port it was received on, but the frame was not forwarded to any port (the PORT_MASK was zero).
- Any data or MAC control frame which matched a unicast, broadcast or multicast address, or matched due to promiscuous mode
- Any length (including less than 64 bytes and greater than RX_MAXLEN bytes)
- had no CRC error, alignment error, or code error
- the destination address was not equal to the source address
- the packet was not destined for the port it was receive on
- had a zero PORT_MASK
