However since qca6174 this has changed. It is now necessary to load specific board file for different designs in driver. The OTP must still be run. Some devices with different subsystem vendor/device ids may share the same board file. Driver could maintain a subsystem vendor/device id to design id however I prefer to just leave this to userspace (e.g. symlinks). Thoughts?

These devices can be differentiated by looking at PCI subsystem device id. That is the case for qca6174 devices at least. Use that and load subsystem id specific board files if possible. Otherwise fall back to use the (old) generic board file path. Using wrong board data may cause device crashes or invalid behaviour (wrong tx power, garbled RF signal).
