How will ath10k find the directory names (or I vendor and > model names) like 'Google' or 'blueline' in this example? I was thinking about the firmware-name = "sdm845/Google/blueline". But this can be really simpler, firmware-name = "blueline" or "sdm845/blueline" with no need for fallbacks. My point is that the firmware-name provides the possibility to handle that in different ways. -- With best wishes Dmitry
