Good CRC enable
When this bit is enabled, AX88180 will receive any packet of good
CRC.
1 = enable
0 = disable
Receive Multicast packet by
lookup hash table
.
When this is enabled, AX88180 will receive multicast packet by the
hash mapping function. It will refer to HASTAB0, HASHTAB1,
HASHTAB2 and HASHTAB3 to look up the table.
1 = enable
0 = disable
Receive Broadcast packet
When this bit is enabled, AX88180 will receive the broadcast packet
1 = enable
0 = disable
Receive Directed Packet.
If this bit is enabled, AX88180 will compare the destination address
field of received packet with the address of MAC (refer to MACID0,
MACID1, MACID2). When it is matched and good CRC, the packet
will be passed to driver. Otherwise it will be dropped.
1 = enable
0 = disable
Receive all Multicast Packets.
If this bit is enabled, any multicast packet (good CRC) will be received
and passed to driver.
1 = enable
0 = disable
Receive Anything.
If this bit is enabled, any packet whether it is good or fail will be
received and passed to driver.
1 = enable
0 = disable
