Field Documentation

◆ match_type

enum rte_swx_table_match_type match_type

Table match type.

Definition at line 39 of file rte_swx_table.h.

◆ key_size

uint32_t key_size

Key size in bytes.

Definition at line 42 of file rte_swx_table.h.

◆ key_offset

uint32_t key_offset

Offset of the first byte of the key within the key buffer.

Definition at line 45 of file rte_swx_table.h.

◆ key_mask0

uint8_t* key_mask0

Mask of key_size bytes logically laid over the bytes at positions key_offset .. (key_offset + key_size - 1) of the key buffer in order to specify which bits from the key buffer are part of the key and which ones are not. A bit value of 1 in the key_mask0 means the respective bit in the key buffer is part of the key, while a bit value of 0 means the opposite. A NULL value means that all the bits are part of the key, i.e. the key_mask0 is an all-ones mask.

Definition at line 55 of file rte_swx_table.h.

◆ action_data_size

uint32_t action_data_size

Maximum size (in bytes) of the action data. The data stored in the table for each entry is equal to action_data_size plus 8 bytes, which are used to store the action ID.

Definition at line 61 of file rte_swx_table.h.

◆ hash_func

Hash function. Ignored when not needed by the table implementation. When needed but set to NULL, the table implementation will select the hash function to use.

Definition at line 67 of file rte_swx_table.h.

◆ n_keys_max

uint32_t n_keys_max

Maximum number of keys to be stored in the table together with their associated data.
