PRO: PACKET_TYPE_PROMISCUOUS. (R/W)  
1: All frames received by the ASIC are forwarded up toward the host.  
0: Disabled (default).  
AMALL: PACKET_TYPE_ALL_MULTICAST. (R/W)  
1: All multicast frames received by the ASIC are forwarded up toward the host, not just the frames whose  
scrambling result of DA matching with multicast address list provided in Multicast Filter Array Register.  
0: Disabled. This only allows multicast frames whose scrambling result of DA field matching with multicast address  
list provided in Multicast Filter Array Register to be forwarded up toward the host (default).  
AB: PACKET_TYPE_BROADCAST. (R/W)  
1: All broadcast frames received by the ASIC are forwarded up toward the host (default).  
0: Disabled.  
AM: PACKET_TYPE_MULTICAST. (R/W)  
1: All multicast frames whose scrambling result of DA matching with multicast address list are forwarded up to the  
host (default).  
0: Disabled.  
AP: Accept Physical Address from Multicast Filter Array. (R/W)  
1: Allow unicast packets to be forwarded up toward host if the lookup of scrambling result of DA is found within  
multicast address list.  
0: Disabled, that is, unicast packets filtering are done without regarding multicast address list (default).  
SO: Start Operation. (R/W)  
1: Ethernet MAC start operating.  
0: Ethernet MAC stop operating (default).  
Drop_CRCE_n: Drop CRC field (FCS:4-byte) of RX packet(R/W)  
1: Don’t drop CRC field.  
0: Drop CRC field (default).  
IPE_n: IP alignmemt enable(R/W)  
1: IP alignmemt enable (default).  
0: IP alignmemt not enable.  
TX_CRC_Pad_n: Padding CRC field in TX packet (R/W)  
1: No padding CRC field in TX packet.  
0: Padding CRC field in TX packet (default).
