This small series enables virtio-net device type in VDUSE. With it, basic operation have been tested, both with virtio-vdpa and vhost-vdpa using DPDK Vhost library series adding VDUSE support using split rings layout (merged in DPDK v23.07-rc1). Control queue support (and so multiqueue) has also been tested, but requires a Kernel series from Jason Wang relaxing control queue polling [1] to function reliably, so while Jason rework is done, a patch is added to fail init if control queue feature is requested.(tested also with DPDK v23.11). Changes in v7: ============== - Fail init only if VIRTIO_NET_F_CTRL_VQ is requested. - Convert to use BIT_ULL() macro - Rebased Changes in v6: ============== - Remove SELinux support from the series, will be handled in a dedicated one. - Require CAP_NET_ADMIN for Net devices creation (Jason). - Fail init if control queue features are requested for Net device type (Jason). - Rebased on latest master. Changes in v5: ============== - Move control queue disablement patch before Net devices enablement (Jason). - Unify operations LSM hooks into a single hook. - Rebase on latest master.
