[ Upstream commit 6d28d577510f1a51f7ffbe830fdbf42077e0058b ]
Like the odroid-c2 and wetek, the s400 uses the RTL8211F and seems to suffer from the kind of stability issue.
Doing an iperf3 download test, we can see a significant number of LPI interrupts on the tx path. After a short while (5 to 15 seconds), the network connection dies. If using rootfs over NFS, the connection may also break during the boot sequence.
We still don't have a real explanation for this problem so let's disable EEE once again.
