class SimDataPath

Defined at line 37 of file ../../src/connectivity/wlan/drivers/third_party/broadcom/brcmfmac/sim/sim_data_path.h

Implements the tx/rx data path for the sim driver using the network device protocol,

and manages the shared memory regions that are used by the protocol.

Note that currently this class does not allow users to transmit or receive in batches.

Frames must be transmitted one at a time.

const std::vector<fuchsia_hardware_network_driver::wire::TxResult> & TxResults ()

Returns all the tx results received since this class was constructed.

Note that there is currently no way to clear the tx results during the lifetime of this class.

const std::vector<std::vector<uint8_t>> & RxData ()

Returns all the received frames since this class was constructed as vectors of bytes.

There is currently no way to clear the rx results during the lifetime of this class.

void Init (fidl::UnownedClientEnd<fuchsia_io::Directory> outgoing_dir_client, fit::callback<void (zx_status_t)> && on_complete)

Initializes and starts the network device.

void TxEthernet (uint16_t id, common::MacAddr dst, common::MacAddr src, uint16_t type, cpp20::span<const uint8_t> body)

Transmit a single ethernet frame. This will internally construct the ethernet header.

The `id` is used to identify the transmitted frame. Tests can keep track of the ids that are

sent and use it to verify that the expected frames were transmitted.

void TxRaw (uint16_t id, const std::vector<uint8_t> & body)

Transmit raw bytes contained in a body.
