The i40e driver is for high throughput (10+Gbps) Intel interfaces. I don't
think you're going to find a simple laptop that has a NIC that uses it. That
would normally be a very custom option for a laptop,

The ixgbe driver also has support for XDP, I believe. (At the very least is has
support for XDP sockets, which usually implies support for basic XDP.) I don't
know if the XDP implementation is as complete with the latest features as i40e,
but it might be a good place to start, and I believe any Intel Gigabit NIC in a
new laptop should use it.

Also, Broadcom has support for XDP (again, I'm not sure how much of the more
recent XDP functionality, though), and there are a lot of laptops that come
with Broadcom NICs.

I think the biggest thing might be to make sure the laptop has a wired ethernet
port. Wireless uses different drivers, and I don't know if any of them have XDP
support, currently. (Maybe they do, but wired is a bit more obvious, and likely
more relevant to your use cases, anyway.)
