Yes the register based injection/extration is not going to be fast, but the FDMA and its driver is being sent later as separate series to keep the size of this review down.FDMA? I need a bit more background here, just to make use this should be a pure switchdev driver and not a DSA driver.
I don't think this should be a DSA driver. As for Ocelot, the CPU port is not a MAC and in that use case, this would be like a top of the rack switch with traffic going to the CPU port being mostly used for managmement (dhcp, stp, etc...) as opposed to being used to forward traffic to another interface, like WAN or wifi. However, I would think there will be cases where the internal CPU is not use and instead use ths switch in a DSA setting, very much like what is done for Felix with regards to Ocelot. -- Alexandre Belloni, Bootlin Embedded Linux and Kernel engineering https://bootlin.com _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
