    i2400m/SDIO: TX and RX path backends · 514ec71f
    Inaky Perez-Gonzalez authored
    Implements the backend so that the generic driver can TX/RX to/from
    the SDIO device.
    
    For RX, when data is ready the SDIO IRQ is fired and that will
    allocate an skb, put all the data there and then pass it to the
    generic driver RX code for processing and delivery.
    
    TX, when kicked by the generic driver, will schedule work on a
    driver-specific workqueue that pulls data from the TX FIFO and sends
    it to the device until it drains it.
    
    Thread contexts are needed as SDIO functions are blocking.
