Excellent dual 10g network
Works perfectly on Linux. Been using it with my 10g netgear switch to share the network connections with multiple VM's on KVM/libvirt. Expensive, but worth it if you need to keep at the bleeding edge of technology, otherwise an overkill. Great to play with sriov, vm's, vf's.

I used this to create a 25 Gb connection from my Threadripper workstation to a Qnap NAS with a SPF+ DAC cable. Speeds are higher and connection is separate from main network.

Worked great for a dual 10G connection from my server to a UniFi switch. True plug-and-play on my Linux build. Much more affordable than the local retail options and the build quality is top-notch. Highly recommend for any home lab or server upgrade.

Works good with opnsense now, its supported from kernel. No problems. Just ordered another one for my 2nd fiber link. It will have almost same kind of opnsense server than my 1st fiber link. This nic is factory unlocked.
