While not particularly related but a good example: if we would provide a better library KPI we could possibly even defer (pseudo-header) checksum calculations to drivers, which expect different calculations already anyway, and even save these cycles on loop as well. Something more to ponder along with other factoring out of drivers etc. /bz -- Bjoern A. Zeeb You have to have visions! It does not matter how good you are. It matters what good you do!
