Support for Aquantia AQC113 and AQC113C Ethernet Controllers on FreeBSD

[Harry-Jing]

Here’s the revised request formatted for a GitHub issue:

Description:

This is a feature request to add driver support for the Aquantia AQC113 and AQC113C Ethernet controllers in FreeBSD. These devices are widely used in modern high-performance networking scenarios, and adding support would enhance FreeBSD's hardware compatibility for servers, NAS systems, and workstations.

Current Behavior:

• The devices are detected by the system but show no driver attached when checked via pciconf or dmesg.
• The aquantia-atlantic-kmod driver does not currently support the AQC113 family.

Example pciconf -lv output:

none3@pci0:7:0:0: class=0x020000 rev=0x03 hdr=0x00 vendor=0x1d6a device=0x14c0 subvendor=0x1d6a subdevice=0x0001
    vendor     = 'Aquantia Corp.'
    device     = 'AQC113C NBase-T/IEEE 802.3an Ethernet Controller [Marvell Scalable mGig]'
    class      = network
    subclass   = ethernet

Expected Behavior:

The AQC113 and AQC113C devices should be recognized and functional under FreeBSD, with support for the advanced features these controllers offer, such as NBase-T and 10GBase-T networking.

Additional Context:

1. Device Details:

   • Vendor: Aquantia Corp. (Marvell)
   • PCI IDs:
     • AQC113: 0x04c0
     • AQC113C: 0x14c0
   • Found in devices like the ASUS XG-C100C v2.

2. Relevant Resources:

   • OpenBSD’s aq driver supports AQC113 and AQC113C (source code).
   • Linux’s atlantic driver includes support for these devices.

3. Use Cases:

   • Deployment in high-performance environments such as NAS systems, workstations, and enterprise servers.
   • Increasing adoption of AQC113-based hardware, particularly for 10G networking.

4. FreeBSD’s Current Limitations:

   • The current aquantia-atlantic-kmod driver supports the AQC107 family but not the AQC113.

Request:

Please consider adding support for the AQC113 family to the aquantia-atlantic-kmod driver or create a new driver for these devices. If testing or hardware access is required, I am happy to assist in debugging and validation.

Logs & System Details:

• FreeBSD Version: 14.1
• Relevant Commands:
  • pciconf -lv: See above example.
  • dmesg | grep -i ethernet: Reports devices as detected but unsupported.

Thank you for your time and consideration. Adding support for the AQC113 family would be a significant enhancement to FreeBSD’s hardware compatibility.
