Just to let everyone on the thread know, I have a fix for this problem that Mike just tested and confirmed. Its funny, its some crufty old code that has been in since I first got TSO working, it checks the packet len on entry to setup, and because I was always working with a standard mtu it had that hardcoded as a value less than which it would reject. I would like to update the 7 code anyway, howbout if I put in a new driver version to HEAD that includes this fix, and then MFC in a few days into REL, is there time before RELEASE or do i just need to spot fix this? Ken? Thanks for testing Mike, Jack
