The Asus XG-C100C 10GBase-T PCIe Network Adapter is one of the still few available 10 gigabit Ethernet adapters, affordable for non-professional use. I thought I’d quickly note down my experience so others can maybe benefit from it.

Debian 9 Stretch

At the time I’m writing the current kernel version in stable is 4.9.88–1 which is enough to make the XG-C100C working (according to the driver readme file >= 3.10).

The latest driver code from Aquantia is available here: - the chip on the Asus NIC is an AQtion AQC107 made by
The drivers I could find on their website were not the latest.

Installing the driver is straight forward just follow the simple instructions in the readme at

And now enjoy your super fast 10gb Ethernet card ;)

Advanced configuration

To use advanced configuration options which are needed for routing/bridging but maybe anyway good advice since the kernel frequently complains about GRO:

TCP: enp1s0: Driver has suspect GRO implementation, TCP performance may be compromised.

ethtool is needed:

sudo apt install ethtool

You can then switch off GRO and LRO with the following commands:

sudo ethtool -K <ethX> gro off
sudo ethtool -K <ethX> lro off

Note for Kernel 4.16 users (i.e. stretch-backports, ubuntu)

There is a bug in <4.16.6 that prevents the card from working properly I had exceptions and kernel faults.
