    wil6210: add support for enhanced DMA RX data flows · 7be13fc3
    Gidon Studinski authored
    Enhanced DMA RX data path is handled using a single
    RX descriptor ring for all VIFs.
    Multiple RX status rings are supported, to allow RSS
    and multi MSI support.
    The driver gets the RX completions via the RX status rings.
    The RX status message includes the completed RX buffer ID,
    which points to the allocated SKB.
    
    The enhanced DMA RX data flow supports RX chaining, where
    multiple SKBs are merged into a single packet.
    
    Enhanced DMA HW supports RX HW reorder offload, enabled by
    default for Talyn-MB.
    
    amsdu_en debugfs entry was added to allow control MSDU aggregation.
    Use the following command to disable AMSDU (enabled by default):
    echo 0 > amsdu_en
