From f15d4dad66374f1b035e2ee59a6495ab4743646a Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Tue, 6 Mar 2001 00:48:59 +0000 Subject: [PATCH] Add in a first pass at ifconfig status reporting. It took a long while hacking on the mess in net-tools-1.59, but it currently adds 12k and supports ethernet, loop, ppp, and treats everything else as a generic interface.
