Aquantia/Marvell AQC107

The AQC107 copper controller is an atlantic device. Multi-rate copper capability and the PCIe host connection are separate links, so both can limit a real transfer independently.

Overview & identity

The driver-local vendor constant is 1d6a and AQC107 is 07b1. The source distinguishes AQC107S and other Aquantia IDs rather than identifying all atlantic devices as AQC107.

Curated identifiers
pci 1d6a:07b1

A numeric match establishes a candidate family within the reviewed evidence. Marketing names, board variants, subsystem conditions and successful operation remain separate questions.

Driver & binding

The atlantic PCI table maps this identity to its hardware revision operations. The upstream guide demonstrates ethtool driver/firmware reporting and separate supported, advertised and current speed fields.

Firmware

Device/revision dependent

The guide shows adapter firmware-version reporting. The inspected PCI table does not establish a universal host-loaded firmware filename for AQC107; resident firmware and board-specific provisioning remain separate.

Read-only diagnostics

Run one displayed command at a time. Replace uppercase placeholders with the affected device, interface or module from your own output. Commands are never executed here. Read-only output can still contain private identifiers.

Check the PCI function and bound driver

lspci -nnk -s BDF

Replace BDF with the domain:bus:device.function address. Look for [1d6a:07b1] and Kernel driver in use. atlantic in Kernel modules is only a candidate, not proof of binding.

Identify the network interface driver

ethtool -i INTERFACE

Replace INTERFACE with the real interface name. Driver and bus-info connect this interface to its device. A displayed firmware-version is adapter information; it does not prove a file was loaded. Candidate: atlantic.

Compare supported modes with the current link

ethtool INTERFACE

Supported/advertised link modes describe capability or negotiation offers. Speed, Duplex and Link detected describe the current link, not measured throughput. An unsupported query is a limitation of the interface/driver.

Separate PCIe transport from Ethernet speed

sudo lspci -vv -s BDF

Elevated access may be needed. Root can expose the full PCI configuration. If PCIe capabilities exist, compare LnkCap with LnkSta: maximum and negotiated PCIe speed/width are different from Ethernet speed. Legacy PCI or virtual functions may omit these fields.

Limitations & related issues

The example output in a guide is not a benchmark or a firmware prescription for this board. Cable quality, switch negotiation and PCIe LnkSta all require actual observations.

These guides are linked for relevant observations, not as known defects of every device in this family.
