You might wish to make sure you try your tests on both big and little endian systems, trying sizes such as 8-bit hash size masks up to something like 16-bit ones. Somewhere deep in the history is the change where Alexey Kuznetsov added those xor+shift statements, noting in the changelog how without it the hash works well on big-endian (which is where I wrote it) but fails spectacularly on little-endian. - 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
