4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jerome Brunet <[email protected]>

[ 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.

board")
