Function Documentation

Fib_AllocBulk()

bool Fib_AllocBulk	(	struct rte_mempool *	fibMp,
		FibEntry *	entries[],
		unsigned	count )

Allocate and zero entries.

Fib_Clear()

void Fib_Clear

(

Fib *

fib

)

Delete all entries.

Precondition

Calling thread is registered as RCU read-side thread, but does not hold rcu_read_lock.

Fib_Erase()

void Fib_Erase	(	Fib *	fib,
		FibEntry *	entry )

Erase given FIB entry.

Precondition

Calling thread holds rcu_read_lock.

Fib_Get()

FibEntry * Fib_Get	(	Fib *	fib,
		LName	name,
		uint64_t	hash )

Retrieve FIB entry.

Precondition

Calling thread holds rcu_read_lock, which must be retained until it stops using the returned entry.

Returns

Virtual or real entry, or NULL if it does not exist.

Fib_Lpm()

FibEntry * Fib_Lpm	(	Fib *	fib,
		const PName *	name )

Perform longest prefix match.

Precondition

Calling thread holds rcu_read_lock, which must be retained until it stops using the returned entry.

Returns

Real entry, or NULL if it does not exist.

Fib_Write()

void Fib_Write	(	Fib *	fib,
		FibEntry *	entry )

Insert or replace a FIB entry.

Parameters

entry

an entry allocated from FIB mempool.

Precondition

Calling thread holds rcu_read_lock.
