Member Function Documentation

   RTE_TAILQ_ENTRY (rte_swx_table_entry)
       Used to facilitate the membership of this table entry to a linked list.

Field Documentation

   uint8_t* key
       Key value for the current entry. Array of key_size bytes or NULL if the key_size for the current table is
       0.

       Definition at line 81 of file rte_swx_table.h.

   uint8_t* key_mask
       Key mask for the current entry. Array of key_size bytes that is logically and'ed with key_mask0 of the
       current table. A NULL value means that all the key bits already enabled by key_mask0 are part of the key
       of the current entry.

       Definition at line 88 of file rte_swx_table.h.

   uint64_t key_signature
       Placeholder for a possible compressed version of the key and key_mask of the current entry. Typically a
       hash signature, its main purpose is to the linked list search operation. Should be ignored by the API
       functions below.

       Definition at line 95 of file rte_swx_table.h.

   uint32_t key_priority
       Key priority for the current entry. Useful for wildcard match (as match rules are commonly overlapping
       with other rules), ignored for exact match (as match rules never overlap, hence all rules have the same
       match priority) and for LPM (match priority is driven by the prefix length, with non-overlapping prefixes
       essentially having the same match priority). Value 0 indicates the highest match priority.

       Definition at line 104 of file rte_swx_table.h.

   uint64_t action_id
       Action ID for the current entry.

       Definition at line 107 of file rte_swx_table.h.

   uint8_t* action_data
       Action data for the current entry. Considering S as the action data size of the action_id action, which
       must be less than or equal to the table action_data_size, the action_data field must point to an array of
       S bytes when S is non-zero. The action_data field is ignored when S is zero.
