intel-ix vs intel-ixv drivers

[Sad Clouds]

I'm having some issues with SR-IOV on FreeBSD-14.3 when using Intel 10G
network adapter and the stock ix(4) driver.

I'd like to try these drivers via packages:
intel-ix-kmod-3.3.35.1403000_2 10 gigabit FreeBSD Base Driver for Intel(R) Network Connections
intel-ixv-kmod-1.5.34.1403000_2 10G FreeBSD Base Driver Virtual Function for Intel(R) NIC

What is the difference between them? Do I need both of them, or
intel-ixv-kmod is just the older version of the same driver?

Thanks.
