I do the driver support for FreeBSD at Myricom. We've supported FreeBSD for quite some time. Our latest PCIXE PCI-X host interfaces support full duplex 4Gb/sec operation. For ethernet encapsulation, you get a big fat pipe that can do 3.85Gb/sec for a single TCP stream (as measured by netperf by me on hosts running 4.8-STABLE). This acts like a normal ethernet interface, and can interect with normal ethernet hosts (assuming approprite protocol conversion in the middle, which we also sell). If you're willing to program to a different API (GM, or MX), you can make use of OS-bypass operation, which reduces host cpu load to near zero at the cost of using a non-sockets API. See our web site for more details. http://www.myri.com/ Currently, our main customer base is large linux clusters that use the OS-bypass side of our nics. It would be nice to get more FreeBSD users. It would certainly make it easier to for me to justify time spent on our FreeBSD drivers ;) Drew
