    net: hns3: refactor dump reset info of debugfs · 1a7ff828
    Jiaran Zhang authored
    Currently, the debugfs command for reset info is implemented by
    "echo xxxx > cmd", and record the information in dmesg. It's
    unnecessary and heavy. To improve it, create a single file
    "reset_info" for it, and query it by command "cat reset_info",
    return the result to userspace, rather than record in dmesg.
    
    The display style is below:
    $cat reset_info
    PF reset count: 0
    FLR reset count: 0
    GLOBAL reset count: 0
    IMP reset count: 0
    reset done count: 0
    HW reset done count: 0
    reset count: 0
    reset fail count: 0
    vector0 interrupt enable status: 0x1
    reset interrupt source: 0x0
    reset interrupt status: 0x0
    RAS interrupt status:0x0
    hardware reset status: 0x0
    handshake status: 0x80
    function reset status: 0x0
    
    Change to the "hclge_show_rst_info" in the "hclge_reset_err_handle",
    when the reset fails, display reset info immediately.
