ot::RouterTable::Contains() const method

A reference to a `Neighbor`.

Removes a link to a neighbor.

Sets the `Info` instance from a given `Neighbor`.

Indicates if a given neighbor matches the address and state filter of `AddressMatcher`.

Signals a "neighbor table changed" event. Invokes the `NeighborTable::Callback` and also signals the change through a related `Notifier` event.

Fills a Route TLV. When @p aNeighbor is not `nullptr`, we limit the number of router entries to `kMaxRoutersInRouteTlvForLinkAccept` when populating `aRouteTlv`, so that the TLV can be appended in a Link Accept message. In this case, we ensure to include router entries associated with @p aNeighbor, leader, and this device itself.

Handles a deferred ack. Some radio links can use deferred ack logic, where a tx request always report `HandleSentFrame()` quickly. The link layer would wait for the ack and report it at a later time using this method. The link layer is expected to call `HandleDeferredAck()` (with success or failure status) for every tx request on the radio link.

Indicates whether the child table contains a given `Neighbor` instance.
