Public Methods
uint16_t rx_notify_threshold ()Returns the device-owned buffer count threshold at which we should trigger RxQueue work. If the
number of buffers on device is less than or equal to the threshold, we should attempt to fetch
more buffers.

uint8_t GetPortSalt (uint8_t base_id)Returns the current port salt for the provided base port ID.
If the port with |base_id| does not currently exist, returns the value of
the previously existing port with the same |base_id| or the initial salt
value.

void SessionStarted (Session & session)Operates workflow for when a session is started. If the session is eligible to take over the
primary spot, it'll be elected the new primary session. If there was no primary session before,
the data path will be started BEFORE the new session is elected as primary,

void SessionStopped (Session & session)Operates workflow for when a session is stopped. If there's another session that is eligible to
take over the primary spot, it'll be elected the new primary session. Otherwise, the data path
will be stopped.

void NotifyTxReturned (bool was_full)Notifies that a batch of Tx frames has been returned.
If was_full is true, all active sessions are notified that device tx space has freed up.

void NotifyDeadSession (Session & dead_session)Called by sessions when they're no longer running. If the dead session has any outstanding
buffers with the device implementation, it'll be kept in `dead_sessions_` until all the buffers
are safely returned and we own all the buffers again.

zx::result<AttachedPort> AcquirePort (netdev::wire::PortId port_id, cpp20::span<const netdev::wire::FrameType> rx_frame_types)Acquires a port for use in a Session.
Sessions are notified of ports that are no longer safe to use by the DeviceInterface through
Session::DetachPort.
NB: The validity of the returned AttachedPort is not really guaranteed by the type system, but
by the fact that DeviceInterface will detach all ports from sessions before continuing.

void TryDelegateRxLease (uint64_t completed_frame_index)Delegates a pending lease to the primary session.
The lease is delegated if |completed_frame_index| is larger than the lease's
hold_until_frame value.
The primary session receives the lease if one exists _and_ the session is
opted in to receive leases. Drops the pending lease immediately otherwise.
