You didn't read what I said. I don't have a gigabit ethernet switch. I only have cards. Therefore the *only* way I can test the operation of the driver and adapters is to connect two machines with gigabit cards back to back with a patch cable. This automatically implies 'using gb end-to-end.' As for corruption due to TCP sequence number wrapping, I don't know what to tell you. I never noticed such behavior in my tests, but that's why I'm asking for feedback from other people. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" ============================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
