I have added a second NIC into the machine, Reatek 8139 rl0 (yes -- I know it's crap), and performed the same setup: maximum speed. Conclusion for me is rather my NIC is broken or the driver. I suspect the driver to be. The link state was going down and up over and over again. The same issue has been reported here [1], [2] a couple of years ago. I will repost this to freebsd-net or rather to bugs.freebsd.org Michael [1] http://forums.nas4free.org/viewtopic.php?t=3606 [2] http://www.mail-archive.com/freebsd-net@freebsd.org/msg11038.html
