This adds support for geting and setting private flags which are driver-specific (and sometimes even model-specific) controls not part of any generic network settings API.
They are used to toggle low-level features in various NICs.
There are currently no tests in this, considering the driver-specific nature of this I am not sure how to best add some. This has been experimentally tested on Linux 6.1 LTS and seems to work fine.
