From b1d757bc1dc29cda592d632b955a706215975f1d Mon Sep 17 00:00:00 2001 From: Alan Somers Date: Fri, 23 Feb 2018 03:11:43 +0000 Subject: [PATCH] libifconfig: multiple feature additions Added the ability to: * Create virtual interfaces * Create vlan interfaces * Get interface fib * Get interface groups * Get interface status * Get nd6 info * Get media status * Get additional ifaddr info in a convenient struct * Get vhids * Get carp info * Get lagg and laggport status * Iterate over all interfaces and ifaddrs And add more examples, too. Note that this is a backwards-incompatible change. But that's ok, because it's a private library.
