I No, it isn't. I previously mentioned the example of a system where the ethernet controller was wired to several PHYs none of which were connected to the data lines. The driver needed to be told to use special PHY detection logic to work on this system. In general anything which may be configured via the SEPROM may need overriding from software on a system without the SEPROM - consulting the datasheet for a USB ethernet controller should give an idea of the things that might need to be configured. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
