On the networking front, instead of TOE, it should be services offload, similar to web load balancer. Offload service base on src/dest addr port proto (tcp/udp). NSO (Network service offload.) - kind of like Apache's reverse proxy with URL rewrite, but maybe for other applications. Question for Leonid of S2io.com: Your company has an interesting card. I think it must have some kind of embedded CPU. Care to tell us what kind of CPU are they? -- -Tony Having a lot of fun with Xilinx Virtex Pro II reconfigurable HW + ppc + Linux - 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/
