Links to mlnx_tune is broken and older version of the script fail with python3

Hi,

I’m trying to follow the performance guidelines at ESPCommunity for example and there is a link to mlnx_tune https://enterprise-support.nvidia.com/s/article/howto-tune-your-linux-server-for-best-performance-using-the-mlnx-tune-tool but it says no page found. Could you update this link or what would be the correct link?

In addition to that, I received an older tar file with mlnx_tune that fails with indentation:

./mlnx_tune
  File "/root/./mlnx_tune", line 161
    IP_FORWARDING_SINGLE_STREAM_SINGLE_PORT = "IP_FORWARDING_SINGLE_STREAM_SINGLE_PORT"
                                                                                       ^
IndentationError: unindent does not match any outer indentation level

I tried to fix it manually but it happens through most of the file. So an updated link to those tools would be helpful.

Thanks
