| 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. |
