I am using the NuttX apps package for the moment, and specifically nsh. So I guess this code handles everything for me. But still, I believe that the MAC address and the IP address belong to different layers of the system. The IP can be handled by the application (as the user may want to do anything with it). On the other hand, the MAC address is a hard-wired address, accessed in a hardware specific way. In my opinion the application shouldn't mess with it and it is best to be set once during the hardware initialization. > I think a PR to bring out the MAC address setup function as was done for > arch/arm/src/samv7/sam_emac.c would be acceptable too.
