Module stm32f7_eth 

embassy-net driver for the STM32F7 ETH MAC + LAN8742A PHY.

Same shape as super::qemu_shm::QemuShmDriver — the differences are all behind the C entry points (ove_stm32f7_eth_async_* vs ove_qemu_net_async_*). For now the driver polls; spawn a poller task alongside the embassy-net Runner:

#[embassy_executor::task]
async fn poll_task() {
    loop {
        embassy_time::Timer::after_millis(2).await;
        ove::async_net::stm32f7_eth::wake_poll();
    }
}

ISR-backed wake (via HAL_ETH_IRQHandler) is a future optimisation — the STM32F7 ETH IRQ exists but stock oveRTOS doesn’t enable it (the lwIP backend also polls).

Structs
