By the way, who is Jack? Is he the author of this driver? I really need to have this feature usable on the driver. I bought these NICs with 82576 chipset for the purpose of implementing IPsec in my network and my current FreeBSD servers could benefit it. Just really thought it has support because FreeBSD was already part of the supported operating system. I was alerted when I've re-read the product info document again that it only support Windows 2008 and Vista platforms. Now, I've confirmed that with the current existing driver. I hope this guy has the plan of implementing it sooner because I really need it. Thanks, Siquijor
