Table 5-343 CPSW_NC_ETH_MAC_PN_INTERVLAN_OPX_D_REG_K Register Field Descriptions

Bit	Field	Type	Reset	Description
31:16	RESERVED	NONE	0h	Reserved
15	DECREMENT_TTL	R/W	0h	Decrement Time To Live - When set, the Time To Live (TTL) field in the header is decremented. IPV4 - Decrement the TTL byte and update the Header Checksum. IPV6 - Decrement the Hop Limit. note: When this bit is set, the ALE should be configured to send any IPv4/6 packet with a zero or one TTL field to the host with the ALE egress operation ttl_check bit.When this bit is cleared the TTL/Hop Limit fields are not checked or modified.
14	DEST_FORCE_UNTAGGED_EGRESS	R/W	0h	Destination VLAN Force Untagged Egress - When set, this bit indicates that the VLAN should be removed on egress for the routed packet. The replace_vid bit should be set for this bit to be used, otherwise force untagged egress comes from the address lookup engine.
13	REPLACE_DA_SA	R/W	0h	Replace Destination Address and Source Address - When set this bit indicates that the routed packet destination address should be replaced by da[47:0] and the source address should be replaced by sa[47:0].
12	REPLACE_VID	R/W	0h	Replace VLAN ID - When set this bit indicates that the VLAN ID should be replaced for the routed packet.
11:0	VID	R/W	0h	VLAN ID
