I appreciate you taking the time, but this isn't quite true For some vendors or kernels, certainly However, this completely disregards the work companies like Intel and AMD do to upstream their drivers, or the leagues of individual maintainers In many cases there is no difference, the driver in the kernel is the upstream one Nvidia has been a notable exception, but they're slowly improving by going (partially?) open source Realtek specifically has problems due to their shared driver core. For example, it often can't reliably tell the difference between an r8125 and r8169
