I have a program that builds under Linux, BSD, and macOS which includes the net/if_arp.h header.
This header does not seem to exist under NuttX. It is included for the ARPHRD_ETHER define (and possibly other things). I see that under NuttX, this is defined in net/arp.h, rather than net/if_arp.h. Is net/if_arp.h supposed to be a standard header? I cannot seem to find any meaningful information about it. Thanks, Nathan
