Even though the Intel cards such as the X520-DA2 and XL710 are not listed on the compatibility list, they seem to work fine as far as I can tell. One limiting factor is the number of lanes. Thunderbolt 3 is Gen3x4 (4 lanes). Some Intel cards (e.g., X520-DA2) are Gen2x8. Thus, this will connect to your laptop as Gen2x4 with the corresponding data rate limits <https://en.wikipedia.org/wiki/PCI_Express#History_and_revisions> (16Gbps). If you are using only a single 10Gbe link, this is not an issue. So, you may want to opt for a NIC with Gen3 capability. Rob
