I tried to write all register information to telemetry data,
but gave up because some drivers had too many registers (eg.ixgbe)
to carry. Therefore, the writing data to file approach is selected.
When we query a register, the register content is the key.
The information such as the width and length is only auxiliary
information. If the register data cannot be obtained, the auxiliary
information is optional. So I don't think register data should be removed.
In my opinion, writing a file is a more appropriate way to do it.
I wonder if there's a better way.
Best regards,
Thanks
