From dd63d3a5b8b312ba042a827441d62458ad63a374 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Eugenio=20P=C3=A9rez?= Date: Thu, 4 May 2023 12:14:47 +0200 Subject: [PATCH] virtio-net: not enable vq reset feature unconditionally MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The commit 93a97dc5200a ("virtio-net: enable vq reset feature") enables unconditionally vq reset feature as long as the device is emulated. This makes impossible to actually disable the feature, and it causes migration problems from qemu version previous than 7.2. The entire final commit is unneeded as device system already enable or disable the feature properly. This reverts commit 93a97dc5200a95e63b99cb625f20b7ae802ba413.
