Hello anybody know if there's something to tweak to get opnsense to see the nerwork interface as 40gbe and not 10gbe ?
Opnsense is on a vm on promox, network card driver is virtio
With virtualised network cards the speed is always as much as the hypervisor and the host can handle. The message from OPNsense is irrelevant. It's a constant text hardwired into the driver.
