This idea has been discussed around here a couple of times, and the consensus is that it is a bad idea: IP (and upper protocol) processing is not expensive, if done right, so this really doesn't buy much; this forces a particular interface to networking into the kernel, loosing flexibility that way is always bad; there is no access to futzing around in between (for example, for firewalling and such); and if the "hardware implementation" has bugs, you are screwed. -- Dr. Horst H. von Brand User #22616 counter.li.org Departamento de Informatica Fono: +56 32 654431 Universidad Tecnica Federico Santa Maria +56 32 654239 Casilla 110-V, Valparaiso, Chile Fax: +56 32 797513 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
