From 3db215d52abd929364fe65da74e2f393ee196818 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Wed, 4 May 2022 15:41:53 +0200 Subject: [PATCH] lib: drive_create_data, drive: remove field "iface" Representing "iface" in the "drive_create_data" and "drive" structures is now useless; the direct backend ignores "iface", while the libvirt one rejects it unless it is empty. Unify both backends -- make them both ignore "iface". (Which only relaxes the libvirt backend, so it cannot cause compatibility problems.) This lets us remove the fields. Update the documentation as well.
