[Arm-dev] wireless mac address

Hello,


I don't know if this is a dev issue/problem,  but I bought 2 RPI 3 about 
a year ago, and installed centos on one (the other one I haven't even 
used yet).

It seems the Mac address changes every reboot? (into something 'random', 
because the first 2 numbers indicate the manufacturer, right?

Is this a known issue?  is it an OS or hardware issue?


thanks,


Ron
