    Anirban Chakraborty authored
    Added code to take FW dump via ethtool. Dump level can be controlled via setting the
    dump flag. A get function is provided to query the current setting of the dump flag.
    Dump data is obtained from the driver via a separate get function.
    
    Changes from v3:
    Fixed buffer length issue in ethtool_get_dump_data function.
    Updated kernel doc for ethtool_dump struct and get_dump_flag function.
    
    Changes from v2:
    Provided separate commands for get flag and data.
    Check for minimum of the two buffer length obtained via ethtool and driver and
    use that for dump buffer
    Pass up the driver return error codes up to the caller.
    Added kernel doc comments.
