Got my ASUS XG-C100C (AQ107) 10GBe card working by updating to the latest OC 0.8.0 with "Prefer Shikumo's Aquantia patch" commit.

Adding the quirk ForceAquantiaEthernet = True to the plist along with DisableIOMapper = false and setting vt-d to enabled in bios
Card works at full 10GBe speed but have lost wifi, handoff and airdrop now.
Edit: VT-d enabled and setting DisableIOMapper = false disables my other network interfaces other then the AQ107
