* Name: neighbor_findentry
|
|
*
|
|
* Description:
|
|
* Find an entry in the Neighbor Table. This interface is internal to
|
|
* the neighbor implementation; Consider using neighbor_lookup() instead;
|
|
*
|
|
* Input Parameters:
|
|
* ipaddr - The IPv6 address to use in the lookup;
|
|
*
|
|
* Returned Value:
|
|
* The Neighbor Table entry corresponding to the IPv6 address; NULL is
|
|
* returned if there is no matching entry in the Neighbor Table.
