## Field Documentation

### struct rte\_rcu\_qsbr\* v

RCU QSBR variable.

Definition at line **102** of file **rte\_hash.h**.

### enum rte\_hash\_qsbr\_mode mode

Mode of RCU QSBR. RTE\_HASH\_QSBR\_MODE\_xxx '0' for default: create defer queue for reclaim.

Definition at line **103** of file **rte\_hash.h**.

### uint32\_t dq\_size

RCU defer queue size. default: total hash table entries.

Definition at line **107** of file **rte\_hash.h**.

### uint32\_t trigger\_reclaim\_limit

Threshold to trigger auto reclaim.

Definition at line **111** of file **rte\_hash.h**.

### uint32\_t max\_reclaim\_size

Max entries to reclaim in one go. default: RTE\_HASH\_RCU\_DQ\_RECLAIM\_MAX.

Definition at line **112** of file **rte\_hash.h**.

### void\* key\_data\_ptr

Pointer passed to the free function. Typically, this is the pointer to the data structure to which the resource to free (key-data) belongs. This can be NULL.

Definition at line **116** of file **rte\_hash.h**.

### rte\_hash\_free\_key\_data free\_key\_data\_func

Function to call to free the resource (key-data).

Definition at line **121** of file **rte\_hash.h**.
