    Wen Gong authored
    For RX, it has two parts, one is to read data from sdio, another
    is to indicate the packets to upper stack. Recently it has only
    one thread to do all RX things, it results that it is sequential
    for RX and low throughout, change RX to parallel for the two parts
    will increase throughout.
    
    This patch move the indication to a workqueue, it results in
    significant performance improvement on RX path.
    
    Udp rx throughout is 200Mbps without this patch, and it arrives
    400Mbps with this patch.
    
    Tested with QCA6174 SDIO with firmware
    WLAN.RMH.4.4.1-00017-QCARMSWPZ-1
