Well, you could use the (sw) bridge functionality of the kernel network stack, but performance naturally wouldn't be as good.

Well, we do have net/dsa, which is conceptually quite similar (even though it has never been extended to hook into the bridging stuff). I agree that we don't have infrastructure to handle hw like cpsw in a really good way today, but it would be very nice to move towards it. -- Bye, Peter Korsgaard -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
