• AQtion AQC100(S): 10G MAC with PCIe Gen3, typically used with SFP+ NICs
• AQtion AQC107/AQC108: 10G (AQC107)/5G (AQC108) multi-gig MAC + Ethernet PHY with PCIe Gen3, for RJ45 Ethernet NICs
• AQtion AQC113/AQC114/AQC114CS/AQC115C: 10G (AQC113)/5G (AQC114/AQC114CS)/2.5G (AQC115C) multi-gig MAC + Ethernet PHY with PCIe Gen4, for RJ45 Ethernet NICs

• PCIe cards
  • TEG-10GECSFP (Version v3.0R) (recommended) - AQC100. Note that earlier versions use a discontinued Tehuti Networks chip
• Thunderbolt
  • QNAP QNA-T310G1S (recommended) - AQC100, JHL6240 PCIe Gen3 x2 TB3 controller. Compact size, fanless
  • Sonnet Solo10G SFP+ - AQC100, JHL6340 PCIe Gen3 x4 TB3 controller. Fanless, has (easily replaceable) captive cable, quite a bit of wasted internal space. Extra two lanes on TB3 controller not useful, and controller has 0.5W higher TDP than the JHL6240. Works fine.

• PCIe cards
• Thunderbolt
  • Sonnet Solo10G (recommended) - AQC107, JHL6340 PCIe Gen3 x4 TB3 controller. Fanless, has (easily replaceable) captive cable. Slightly shorter than Solo10G SFP+ (see above).
  • QNAP QNA-T310G1T - AQC107, JHL6240 PCIe Gen3 x2 TB3 controller. Has an internal fan. Compact size; form factor similar to QNA-T310G1S (see above).

Why not just use something like an Intel i225?

• atlflashupdate (Linux)¹⁾
  • Extract and copy the atlflashupdate binary to the Windows firmware package and execute there
• aqcdiag²⁾ - self-tests, flash backup/restore, device info, etc
  • It's a bit old, so the Linux version links old libraries and references old kernel header files.
    • On Ubuntu 22.04, using DIAG_2.10_Ubuntu_x86_64.zip, patching lib/_ctypes.x86_64-linux-gnu.so to use libffi.so.7 instead of libffi.so.6, and patching lib/readline.x86_64-linux-gnu.so to use libreadline.so.8 instead of libreadline.so.6 seems to work fine.
    • Replace #include <asm/compat.h> with #include <linux/compat.h> in diag_driver_linux/diag_driver.c for newer kernel versions too.
  • Or you can use this patched archive: build the kernel driver in driver/diag_driver_linux with make, then run ./DIAG -s (to automatically unload/load kernel modules) in diag/.
  • To backup/restore flash: use menu item 3) Flash → 3) Save Flash Contents To File (read) or 2) Update Flash Image (write).
  • ./DIAG -s –password \!h:ahT8uW6 also exposes secret menus that let you read/write registers, update PCIe device ID/subsystem IDs, change MAC addresses, wipe your flash (!), etc

• AQC100/AQC10x/AQC11x: Marvell Drivers → Marvell Public Drivers → Windows → AQC107
