The dev_octeon_virtio_plugin.so plugin is not included in the VPP Debian package (vpp-25.02.0-cn10k-devel). The plugin is absent, preventing VirtIO-based use cases from being configured.
NGINX fails to respond during curl/ab load tests when using CPT for crypto offload and VPP for user-space TCP processing.
