This asks for the equivalent of "eth0", but asks the OS to tell us the actual name. I don't know that we can possibly choose the correct network interface to use across any machine configuration. Choosing the first one, whatever it's name is, seems like a pretty reliable way to get a good interface in most cases. > > Regards, > Simon > _______________________________________________ > U-Boot mailing list > [email protected] > https://lists.denx.de/listinfo/u-boot _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
