Description
Under System/Advanced/Networking there is an option to deactivate ALTQ for Microsoft Hyper-V hn vNICs. It would be good to have this as well for VTNET (VirtIO Networking) vNICs, to allow the use of Multiqueue.
This used to be impossible, as ALTQ support was a Compiletime option, that deactivated Multiqueue support. I created a pull request which was merged into FreeBSD yesterday, which now allows deactivating ALTQ, using the loader tunable hw.vtnet.altq_disable, and instead allowing Multiqueue in the VTNET driver.

This isn't quite working, it's leaving duplicate entries in loader.conf and somehow ending up always being 0 no matter the setting.
Fixing the cleanup seems to correct it.

One more little bug here. The page isn't configuring the loader variables on save if there are changes, so the change isn't reflected on the next boot, but the one after.

Seems to work as expected when set properly now. If the VM NIC is configured with multiple queues, and this option is unchecked, then the OS sees multiple queues for the NIC. Single queue otherwise no matter the VM config when checked.

Works fully as expected on the latest snapshot.
