gadget mode ethernet - the mac address
so if designing a product and want only method of update to be plug in via usb on a zero-w based device otherwise operating in ap mode (don't want to mess with knowledge of client-to-host wifi password and implications)
but to get gadget mode working always providing same mac to host so it always uses the network connection settings you have set a fixed mac address twice on pi (the one the usb port pi plugs into's root mac and the pi's root mac)
is there a raspberry pi mac address that could be used that would be like still trusted! like a kind of trusted untrusted mac address that first N bytes identify as raspberry pi, rest are like pi-product address space...
or even better a method of assigning a full mac address to a generic multiple instance product????
one of those ironies, start logging things with paranoia, start worrying about things you do not recognise/remember you did eh!
like asking someone to set up a new network connection everytime the otg auto mac generation sets up and leave N connection settings on host machine is like... well an interesting problem, at what level of (customer) skill does someoene realise what is going on? and why? and who? and where? and when? etc. and even whether to worry about eh LOL!
