+ Here is the caller graph for this function:

u8* format_vnet_sw_if_index_name_with_NA ( u8 s,
va_list *  args 
)

Format sw_if_index.

If the value is ~0, use the text "N/A"

Add an entry to the l2fib.

If the entry already exists then overwrite it

Compute the hash for the given key and return the corresponding bucket index.

Definition at line 80 of file l2_fib.h.

u32 l2fib_del_entry ( u64  mac,
u32  bd_index 
)

Delete an entry from the l2fib.

Return 0 if the entry was deleted, or 1 if it was not found

u8 mac0,
u16  bd_index0,
l2fib_entry_key_t key0,
u32 bucket0,
l2fib_entry_result_t result0 
)

Lookup the entry for mac and bd_index in the mac table for 1 packet.

Cached_key and cached_result are used as a one-entry cache. The function reads and updates them as needed.

mac0 and bd_index0 are the keys. The entry is written to result0. If the entry was not found, result0 is set to ~0.

key0 and bucket0 return with the computed key and hash bucket, convenient if the entry needs to be updated afterward. If the cached_result was used, bucket0 is set to ~0.

Lookup the entry for mac and bd_index in the mac table for 2 packets.

The lookups for the two packets are interleaved.

Cached_key and cached_result are used as a one-entry cache. The function reads and updates them as needed.

mac0 and bd_index0 are the keys. The entry is written to result0. If the entry was not found, result0 is set to ~0. The same holds for mac1/bd_index1/result1.
