I have lost track how many times I mentioned it. I am not going to mention it anymore and I will not review this patch until review comments are actually addressed. It is a blind disrespect towards the maintainers and reviewers. Regards Marcel

the RF performance of wcn6855 soc chip from different foundries will be difference, so we should use different nvm to configure them.
