Hello,

This patch needs to be backported to the stable 6.1.x and 6.64.x branches, as the initial patch https://github.com/torvalds/linux/commit/e269d79c7d35aa3808b1f3c1737d63dab504ddc8 was backported a few days ago: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/include/linux/virtio_net.h?h=3Dv6.1.103&id=3D5b1997487a3f3373b0f580c8a20b56c1b64b0775
