    usb: gadget: u_ether: move hardware transmit to RX NAPI · 716fb91d
    Weinn Jheng authored
    In order to reduce the interrupt times in the embedded system,
    a receiving workqueue is introduced.
    This modification also enhanced the overall throughput as the
    benefits of reducing interrupt occurrence.
    
    This work was derived from previous work:
    u_ether: move hardware transmit to RX workqueue.
    Which should be base on codeaurora's work.
    
    However, the benchmark on my platform shows the throughput
    with workqueue is slightly better than NAPI.
