Ethernet MAC will stop writing further data in the frame to memory; the FailFilter bit in the
status word of the frame will be set to indicate that the software device driver can discard
the frame immediately.
Unicast, broadcast and multicast
Generic filtering based on the type of frame (unicast, multicast or broadcast) can be
programmed using the AcceptUnicastEn, AcceptMulticastEn, or AcceptBroadcastEn bits
of the RxFilterCtrl register. Setting the AcceptUnicast, AcceptMulticast, and
AcceptBroadcast bits causes all frames of types unicast, multicast and broadcast,
respectively, to be accepted, ignoring the Ethernet destination address in the frame. To
program promiscuous mode, i.e. to accept all frames, set all 3 bits to 1.
Perfect address match
When a frame with a unicast destination address is received, a perfect filter compares the
destination address with the 6 byte station address programmed in the station address
registers SA0, SA1, SA2. If the AcceptPerfectEn bit in the RxFilterCtrl register is set to 1,
and the address matches, the frame is accepted.
