bool IsDataVmoPrepared (uint8_t vmo_id)Defined at line 101 of file ../../src/connectivity/network/drivers/network-device/device/device_interface.h

number of buffers on device is less than or equal to the threshold, we should attempt to fetch
more buffers.

value.

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 session.
The lease is delegated if |completed_frame_index| is larger than the lease's
hold_until_frame value.
The session receives the lease if one exists _and_ the session is
opted in to receive leases. Drops the pending lease immediately otherwise.
