The Ethernet address fields of an Ethernet Packet, consists of two 6-byte fields: one for the destination
address and one for the source address. The first bit of the destination address signifies whether it is
a physical address or a multicast address.
The LAN9215 address check logic filters the frame based on the Ethernet receive filter mode that has
been enabled. Filter modes are specified based on the state of the control bits in
Filtering
bits are defined in more detail in the “MAC Control Register”. Please refer to
"MAC_CR—MAC Control Register," on page 99
If the frame fails the filter, the Ethernet MAC function does not receive the packet. The host has the
option of accepting or ignoring the packet.
