OK. Now, as I'm lookig at this issue it seemed like there _ought_ to be an issue with RNDIS ... except that I see the RNDIS code actually copies every packet to get rid of its special headers. And it doesn't even use memcpy to do it!! Bleech. After all that work to get rid of all memcpy calls, and then that one's in the critical path. Oh well; at least the TX path, and RX from non-Windows hosts, is quick! - Dave ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
