Name:___neigh_lookup_noref

Proto:static inline struct neighbour *___neigh_lookup_noref(struct neigh_table *tbl, bool (*key_eq)(const struct neighbour *n, const void *pkey), __u32 (*hash)(const void *pkey, const struct net_device *dev, __u32 *hash_rnd), const void *pkey, struct net_device *dev)

Type:struct neighbour

Parameter:

Type	Parameter	Name
struct neigh_table *	tbl
bool (*	key_eq
__u32 (*	hash
const void *	pkey
struct net_device *	dev

289

nht = fetch an RCU-bh-protected pointer for dereferencing(nht)

293

hash_val = hash(pkey, dev, hash_rnd) >> 32 - hash_shift

294

When n != NULL cycle

297

If dev == dev && key_eq(n, pkey) Then Return n

301

Return NULL
