@phil47 and @Flyer By way of a test here I’ve just updated to 3.8.15-9 testing channel on an ASRock N3700-ITX motherboard.
I agree with @Flyer to leave for time being given you are busy populating data drives.
The kernel version on my ASRock is now:
uname -a
Linux cube 4.8.7-1.el7.elrepo.x86_64 #1 SMP Thu Nov 10 20:47:24 EST 2016 x86_64 x86_64 x86_64 GNU/Linux
and the Ethernet controller is:
lspci | grep Ethernet
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 11)
The install is bios based not UEFI.
lsmod | grep r8169
r8169 81920 0
mii 16384 1 r8169
All appears to be OK currently.
From my desktop:
iperf -c cube.lan

Client connecting to cube.lan, TCP port 5001

with the following command running on the rockstor machine “cube.lan”:
iperf -s
‘Ctrl + c’ to cancel the running iperf -s on the Rockstor.
Adding details here by way of test on similar hardware.
