These chips allow this too, Microsoft defined a standard for RX queue interrupt hashing by flow so everyone puts it, or something like it, in hardware. > In the extreme case it would be cool if it were possible to push a > bpf-like classifier down into the hardware to allow arbitrary kinds of > flow distribution. Maybe not a fully bpf, but many chips allow something close. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
