Acl_Port_Ace_Map_Table
Description: This table converts ACE map index values derived from TCP port indexes into ACE maps.
Table 76. Acl_Port_Ace_Map_Table Register Parameters
Table 77. Acl_Port_Ace_Map_Table Field Parameters
This table is addressed by Acl_Port_Ace_Map_Index_Table.port_ace_map_index[7:0] and returns the
64-bit ACE map value for the associated TCP port. An ACE map is a vector that identifies all of the ACEs for which
the associated TCP port number range registers a match.
The following figure shows where this table fits in the ACL processing pipeline.
