Description

In current versions of pfSense (2.7.0, 23.05.1) multiqueue support for virtio NIC has vanished. Apparently this was done to support ALTQ. This is a serious new limitation for high throughput virtualized routers. Please re-add support for multiqueue on virtio. If this is driver limitation please at least allow us to choose between ALTQ or multiqueue enabled drivers for vitio like it is for other NIC's in pfsense.

Not sure whether this is a bug or request for a feature to be re-added.

I second this request, can't get more than ~2.5Gbps out of interfaces because of this, which is really annoying.
Was debugging a bunch of stuff and this appears to be the root cause.

I'd appreciate if maintainers could take a look at this

The issue is discussed in this forum thread https://forum.netgate.com/topic/138174/pfsense-vtnet-lack-of-queues. However, the last post dates all the way back to March 2021. Any chance we can get an update on this issue?
