typedefvoid*(*rte_table_op_create)(void*params,intsocket_id,uint32_tentry_size)
Lookup table create
Parametersparams Parameters for lookup table creation. The underlying data structure is different for each
lookup table type.
socket_id CPU socket ID (e.g. for memory allocation purpose)
entry_size Data size of each lookup table entry (measured in bytes)
Returns
Handle to lookup table instance

typedefint(*rte_table_op_free)(void*table)
Lookup table free

Returns
0 on success, error code otherwise

typedefint(*rte_table_op_entry_add)(void*table,void*key,void*entry,int*key_found,void**entry_ptr)
Lookup table entry add
Parameterstable Handle to lookup table instance
key Lookup key
entry Data to be associated with the current key. This parameter has to point to a valid memory
buffer where the first entry_size bytes (table create parameter) are populated with the data.
key_found After successful invocation, *key_found is set to a value different than 0 if the current
key is already present in the table and to 0 if not. This pointer has to be set to a valid memory
location before the table entry add function is called.
entry_ptr After successful invocation, *entry_ptr stores the handle to the table entry containing the
data associated with the current key. This handle can be used to perform further read-write accesses
to this entry. This handle is valid until the key is deleted from the table or the same key is re-
added to the table, typically to associate it with different data. This pointer has to be set to a
valid memory location before the function is called.
Returns
0 on success, error code otherwise

typedefint(*rte_table_op_entry_delete)(void*table,void*key,int*key_found,void*entry)
Lookup table entry delete
Parameterstable Handle to lookup table instance
key Lookup key
key_found After successful invocation, *key_found is set to a value different than 0 if the current
key was present in the table before the delete operation was performed and to 0 if not. This pointer
has to be set to a valid memory location before the table entry delete function is called.
entry After successful invocation, if the key is found in the table (*key found is different than 0
after function call is completed) and entry points to a valid buffer (entry is set to a value
different than NULL before the function is called), then the first entry_size bytes (table create
parameter) in *entry store a copy of table entry that contained the data associated with the current
key before the key was deleted.
Returns
0 on success, error code otherwise

typedefint(*rte_table_op_entry_add_bulk)(void*table,void**keys,void**entries,uint32_tn_keys,int*key_found,void**entries_ptr)
Lookup table entry add bulk
Parameterstable Handle to lookup table instance
keys Array containing lookup keys
entries Array containing data to be associated with each key. Every item in the array has to point to
a valid memory buffer where the first entry_size bytes (table create parameter) are populated with
the data.
n_keys Number of keys to add
key_found After successful invocation, key_found for every item in the array is set to a value
different than 0 if the current key is already present in the table and to 0 if not. This pointer has
to be set to a valid memory location before the table entry add function is called.
entries_ptr After successful invocation, array *entries_ptr stores the handle to the table entry
containing the data associated with every key. This handle can be used to perform further read-write
accesses to this entry. This handle is valid until the key is deleted from the table or the same key
is re-added to the table, typically to associate it with different data. This pointer has to be set
to a valid memory location before the function is called.

typedefint(*rte_table_op_entry_delete_bulk)(void*table,void**keys,uint32_tn_keys,int*key_found,void**entries)
Lookup table entry delete bulk
Parameterstable Handle to lookup table instance
keys Array containing lookup keys
n_keys Number of keys to delete
key_found After successful invocation, key_found for every item in the array is set to a value
different than 0if the current key was present in the table before the delete operation was performed
and to 0 if not. This pointer has to be set to a valid memory location before the table entry delete
function is called.
entries If entries pointer is NULL, this pointer is ignored for every entry found. Else, after
successful invocation, if specific key is found in the table (key_found is different than 0 for this
item after function call is completed) and item of entry array points to a valid buffer (entry is set
to a value different than NULL before the function is called), then the first entry_size bytes (table
create parameter) in *entry store a copy of table entry that contained the data associated with the
current key before the key was deleted.

typedefint(*rte_table_op_lookup)(void*table,structrte_mbuf**pkts,uint64_tpkts_mask,uint64_t*lookup_hit_mask,void**entries)
Lookup table lookup
Parameterstable Handle to lookup table instance
pkts Burst of input packets specified as array of up to 64 pointers to struct rte_mbufpkts_mask 64-bit bitmask specifying which packets in the input burst are valid. When pkts_mask bit n
is set, then element n of pkts array is pointing to a valid packet. Otherwise, element n of pkts
array does not point to a valid packet, therefore it will not be accessed.
lookup_hit_mask Once the table lookup operation is completed, this 64-bit bitmask specifies which of
the valid packets in the input burst resulted in lookup hit. For each valid input packet (pkts_mask
bit n is set), the following are true on lookup hit: lookup_hit_mask bit n is set, element n of
entries array is valid and it points to the lookup table entry that was hit. For each valid input
packet (pkts_mask bit n is set), the following are true on lookup miss: lookup_hit_mask bit n is not
set and element n of entries array is not valid.
entries Once the table lookup operation is completed, this array provides the lookup table entries
that were hit, as described above. It is required that this array is always pre-allocated by the
caller of this function with exactly 64 elements. The implementation is allowed to speculatively
modify the elements of this array, so elements marked as invalid in lookup_hit_mask once the table
lookup operation is completed might have been modified by this function.

0 on success, error code otherwise

typedefint(*rte_table_op_stats_read)(void*table,structrte_table_stats*stats,intclear)

Parameterstable Handle to lookup table instance
stats Handle to table stats struct to copy data
clear Flag indicating that stats should be cleared after read
Returns
Error code or 0 on success.
