With all of this development activity, I certainly hope that the baseline for modern ATX motherboards, is AT LEAST 2.5GbE-T, if not 5GbE-T, especially if it only takes a single PCI-E 3.0 lane.

Yeah, just knew that Aquantia was acquired by Marvell.

Did find AQC111C & AQC112C chipset info.

AQC111C: 5Gbps PCIe gen3/gen2 x1
(appears in ASUS Z390 gaming motherboard ROG MAXIMUS XI EXTREME & FORMULA)
AQC112C: 2.5Gbps PCIe gen3/gen2 x1


I might have been wrong, about AQC107/108 being pure PCIe 2.0 designs: Evidently they *do* support PCIe 3 8GT/s speeds, too. So you could in theory be able to operate 10Gbit Ethernet on just two PCIe 3.0 lanes... except that nobody offers such a slot.

Here are the links to the product descriptions:
ACQ107/108 (PCIe 2/3 x4, up to 10Gbit Ethernet)
ACQ111C/112C (PCIe 3 x1, up to 5Gbit Ethernet)
ACQ111U/112U (USB 3, up to 5Gbit Ethernet)

So they all come from a single family of chips (and lithography), like their switch counterparts, three of which are inside my Buffalo 12-port switch for an NBase-T core:
AQR407/AQR408/AQR409 (10/5/2.5 Gibt 4-port switch chips)
