However, I have had numerous ethernet chips over the years which produced these errors every now and again, and I have always safely ignored them. Run some stress tests before you ship the machine, but if you get decent(*) performance then I'd just ship it without being concerned. --Alex (*) Decent, is of course not likely to be Gigabit! Try the nttcp port for measuring the performance you get; ftp performance will likely be limited by disk-read; and ssh is just rubbish on fast networks unless you install ssh-hpn port which fixes some problems and also adds the ability to not encrypt the data transfer (just the authentication) which is useful on closed-ish networks.
