Jumping in late.. (please CC, not on the list) As the other posters have suggested, you _can_ use this switch without any special drivers. Your boot loader should initialise it in such a way that the CPU port is treated as just another switch port (turn tag mode off, and force link/speed/duplex since there is no PHY), and then it'll be just as if your CPU is connected to a regular 7-port ethernet switch. If you want more control over the switch, I've just posted a patch series to the linux netdev mailing list for support for various DSA switches. (There is no 88E6063 support yet, but there is support for the 88E6060, and 6063 shouldn't be hard to add.) What that patch series does is to expose each port on the switch as a linux network interface, handling things like link state, PHY commands and hardware statistics transparently, as if the switch ports were individual NICs in the host system. A forthcoming patch set will handle hardware bridging transparently, so if you do e.g. "brctl addif br0 lan1; brctl addif br0 lan2", the DSA driver will program the switch chip so that ports 1 and 2 will be bridged in hardware, etc. >From a software point of view, the only difference between the 88E6060 and the 88E6063 is that the 6063 has hardware QoS and hardware stats counters. If you'd like to give it a go, let me know and I'll whip up a 88E6063 support patch for you to try. -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
