Problem Description:

The buildroot used to build openvswitch3.5 is outdated and does not contain the linux/vduse.h Linux Kernel header. The consequence is that

 Impact Assessment:

VDUSE support is not built in openvswitch3.5 whereas all dependencies are met at runtime (VDUSE is supported in Kernel 9.6).

 Software Versions: openvswitch3.5-3.5.0-0.11.el9fdp

  Issue Type: New issue

 Reproducibility: 100%

 Reproduction Steps:

1. Generate an opnvswitch3.5 build

2. install the RPM and start openvdwitch

3. add a VDUSE port, and get this message:

1. ovs-vsctl add-port br0 vduse0 – set Interface vduse0 type=dpdkvhostuserclient options:vhost-server-path=/dev/vduse/vduse0
   ovs-vsctl: Error detected while setting up 'vduse0': could not add network device vduse0 to ofproto (Invalid argument). See ovs-vswitchd log for details.
   ovs-vsctl: The default log directory is "/var/log/openvswitch".
    

    Expected Behavior:

Adding a VDUSE port should work

 Observed Behavior:

1. ovs-vsctl add-port br0 vduse0 – set Interface vduse0 type=dpdkvhostuserclient options:vhost-server-path=/dev/vduse/vduse0
   ovs-vsctl: Error detected while setting up 'vduse0': could not add network device vduse0 to ofproto (Invalid argument). See ovs-vswitchd log for details.
   ovs-vsctl: The default log directory is "/var/log/openvswitch".
