The sequence shown in Figure 43-13 is valid when all the filters (L2, VLAN, L3, L4) are active. If any of the Layer filters are not enabled, that filter is bypassed and the subsequent filter is applied. A packet that fails any of the filters is discarded. However, the discarded packet can be forwarded to the host based on the register control. For example, when Bit RA of MAC_Packet_Filter register is set to 1, all discarded packets are forwarded to the host but with its packet status indicating the specific filter-failure. If RA=0, Bits VTFE and IPFE of MAC_Packet_Filter register controls if the packets that fail the VLAN filter and Layer 3-4 filter should be discarded or forwarded to the host.
