L3HDBM0=B_0x0_IPV4_PACKETS, L3HSBM0=B_0x0_IPV4_PACKETS
L3 and L4 control 0 register
| L3PEN0 | Layer 3 Protocol Enable When this bit is set, the Layer 3 IP Source or Destination Address matching is enabled for IPv6 packets. When this bit is reset, the Layer 3 IP Source or Destination Address matching is enabled for IPv4 packets. The Layer 3 matching is done only when the L3SAM0 or L3DAM0 bit is set. |
| L3SAM0 | Layer 3 IP SA Match Enable When this bit is set, the Layer 3 IP Source Address field is enabled for matching. When this bit is reset, the MAC ignores the Layer 3 IP Source Address field for matching. Note: When the L3PEN0 bit is set, you should set either this bit or the L3DAM0 bit because either IPv6 SA or DA can be checked for filtering. |
| L3SAIM0 | Layer 3 IP SA Inverse Match Enable When this bit is set, the Layer 3 IP Source Address field is enabled for inverse matching. When this bit reset, the Layer 3 IP Source Address field is enabled for perfect matching. This bit is valid and applicable only when the L3SAM0 bit is set. |
| L3DAM0 | Layer 3 IP DA Match Enable When this bit is set, the Layer 3 IP Destination Address field is enabled for matching. When this bit is reset, the MAC ignores the Layer 3 IP Destination Address field for matching. Note: When the L3PEN0 bit is set, you should set either this bit or the L3SAM0 bit because either IPv6 DA or SA can be checked for filtering. |
| L3DAIM0 | Layer 3 IP DA Inverse Match Enable When this bit is set, the Layer 3 IP Destination Address field is enabled for inverse matching. When this bit is reset, the Layer 3 IP Destination Address field is enabled for perfect matching. This bit is valid and applicable only when the L3DAM0 bit is set high. |
| L3HSBM0 | Layer 3 IP SA higher bits match This field contains the number of lower bits of IP source address that are masked for matching in the IPv4 packets. The following list describes the values of this field: … Condition: IPv6 packets: This field contains Bits[4:0] of L3HSBM0. These bits indicate the number of higher bits of IP source or destination address matched in the IPv6 packets. This field is valid and applicable only when the L3DAM0 or L3SAM0 bit is set high. 0 (B_0x0_IPV4_PACKETS): No bits are masked. 1 (B_0x1_IPV4_PACKETS): LSb[0] is masked |
| L3HDBM0 | Layer 3 IP DA higher bits match This field contains the number of higher bits of IP Destination Address that are masked in the IPv4 packets: … Bits[12:11] of this field correspond to Bits[6:5] of L3HSBM0 which indicate the number of lower bits of IP Source or Destination Address that are masked in the IPv6 packets. Number of bits masked is given by concatenated values of the L3HDBM0[1:0] and L3HSBM0 bits: … This field is valid and applicable only when the L3DAM0 or L3SAM0 bit is set. 0 (B_0x0_IPV4_PACKETS): No bits are masked. 1 (B_0x1_IPV4_PACKETS): LSb[0] is masked |
| L4PEN0 | Layer 4 Protocol Enable When this bit is set, the Source and Destination Port number fields of UDP packets are used for matching. When this bit is reset, the Source and Destination Port number fields of TCP packets are used for matching. The Layer 4 matching is done only when the L4SPM0 or L4DPM0 bit is set. |
| L4SPM0 | Layer 4 Source Port Match Enable When this bit is set, the Layer 4 Source Port number field is enabled for matching. When this bit is reset, the MAC ignores the Layer 4 Source Port number field for matching. |
| L4SPIM0 | Layer 4 Source Port Inverse Match Enable When this bit is set, the Layer 4 Source Port number field is enabled for inverse matching. When this bit is reset, the Layer 4 Source Port number field is enabled for perfect matching. This bit is valid and applicable only when the L4SPM0 bit is set high. |
| L4DPM0 | Layer 4 Destination Port Match Enable When this bit is set, the Layer 4 Destination Port number field is enabled for matching. When this bit is reset, the MAC ignores the Layer 4 Destination Port number field for matching. |
| L4DPIM0 | Layer 4 Destination Port Inverse Match Enable When this bit is set, the Layer 4 Destination Port number field is enabled for inverse matching. When this bit is reset, the Layer 4 Destination Port number field is enabled for perfect matching. This bit is valid and applicable only when the L4DPM0 bit is set high. |
