Byte Conversion
    [Documentation]   Byte Conversion method receives IPMI RAW commands as
    ...               argument in string format.
    ...               Sample argument is as follows
    ...               "0x04 0x30 9 0x01 0x00 0x35 0x00 0x00 0x00 0x00 0x00
    ...               0x00"
    ...               IPMI RAW command format is as follows
    ...               <netfn Byte> <cmd Byte> <Data Bytes..>
    ...               This method converts IPMI command format into
    ...               dbus command format  as follows
    ...               <byte:seq-id> <byte:netfn> <byte:lun> <byte:cmd>
    ...               <array:byte:data>
    ...               Sample dbus  Host IPMI Received Message argument
    ...               byte:0x00 byte:0x04 byte:0x00 byte:0x30

#   To Check scenario for smaller IPMI raw commands with only 2 arguments

#   Sample small IPMI raw command: Run IPMI command 0x06 0x36
#   If IPMI raw argument length is only 9 then return value in bytes without

Copy ipmitool
    OperatingSystem.File Should Exist   tools/ipmitool      msg=The ipmitool program could not be found in the tools directory. It is not part of the automation code by default. You must manually copy or link the correct openbmc version of the tool in to the tools directory in order to run this test suite.
