I have a pc with a Ethernet controller: Qualcomm Atheros AR8161 Gigabit Ethernet (rev 10)
At the moment I am running kernel 3.10.10 with the alx driver compiled into the kernel.

The card works just fine, but the issue that I am having is that the traffic counters are not updated.
Both ifconfig and /proc/net/dev show only zeroes.

Example output, AR8161 interface is enp2s0:
Code:
titan ~ # cat /proc/net/dev

        Kernel driver in use: alx



Does anyone know if this is a driver issue, or did I forget to activate some kernel parameter?

Apparently the driver in the kernel has been stripped down to the bare minimum.
There are still no traffic counters in kernel 3.11.4
