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 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.

bool PrepareRxVmos (RxVmoList::iteratorstart,RxVmoList::iterator *in_out_end,fit::callback<void (fit::result<std::tuple<zx_status_t, DataVmoList>>)>cb)
Submits a batch of Rx VMOs for preparation. It skips any VMO that has already been prepared.
Returns whether the batch is already prepared.
|in_out_end| specifies the end of the range on input, and on output is set to the iterator
past the last VMO submitted for preparation before any lock is released, or to |start| if
nothing could be prepared.
Defined at line 1297 of file ../../src/connectivity/network/drivers/network-device/device/device_interface.cc
bool ReleaseRxVmo (DataVmoMeta & vmo)Attempts to release the Rx VMO. Returns true if the VMO has successfully transitioned to
VmoState::kReleasing (meaning a release operation is now pending or starting). Returns false if
the release attempt failed (e.g., the VMO is also registered for Tx, not currently prepared,
or the session is invalid).
