The original thread appeared in Issue 36, "ifconfig reports TX errors on v2.1.x kernels.".
From Peter Bruley on Mon, 04 Jan 1999
I've posted the question to a few groups and have not yet heard any replies.
Actually I looked into it a bit more --- read the Linux Kernel Mailing List FAQ at http://www.tux.org/lkml and you'll find that this is a known problem between the new kernels and an older version if 'ifconfig' --- update your binaries as recommended in the LKML.FAQ.
Your "one-stop" shopping center for getting all the requisite user space program updates for your 2.2 kernel would be at LinuxHQ (http://www.linuxhq.com/pgmup21.html)
Hope that helps.
