I'm using the 0.9.6 driver with 6.1 RELEASE. I don't use jumbo frames, so the only problem I've experienced is the link state going up and down occasionally. Does the more current driver solve the link state problem? If it does, can I use it on 6.1 merely by replacing the three files included with it? Or are there includes that refer to other libraries that have changed since 6.1? Am I better off upgrading the entire system to 6.2? (I prefer not to do this, because I have to take the site down to do so. Patching files and rebuilding world and kernel only takes the box out of service during the reboots. -- Paul Schmehl (pauls@utdallas.edu) Senior Information Security Analyst The University of Texas at Dallas http://www.utdallas.edu/ir/security/help
