GbE Ethernet Port Issue Data Gathering Statistics Intel

[pfeerick]

1) Pine64+ (1GB)  - A64-DB-Rev B (2016-02-24)
2) RTL chip numbers:  RTL8211E 'Green' (RTL8211E G2M97H2 GG09B)
3) Router/Modem: Billion 7800NXL, Switch: Tenda  1008D (not currently in service, but when used makes no difference)
4) if you modded your board and made it work, how? N/A
5) if you swapped out your switch or router and made it work, what or which? N/A
6) if GbE is critical to your operation, please tell us how so ? Currently not, but if pine64 replaces my current NAS solution, will be needed due to frequent large file transfers
7) provide any other additional 'data only' that might be helpful.

In my (working) case, both router and switch support GbE (1000T ethernet). Both router and switch will acknowledge successful GbE autonegotation with pine64. This on debian, with the  v3.10.101-4-pine64-longsleep kernel. 

When I shut down my normal (onboard) wireless link, and switch to eth0, I get the results listed below. Nowhere near as fast as GbE can go, but a significant amount faster than 100M ethernet, using what ethernet cabling I had handy. I issued a 'sudo ifup eth0' command to bring up the ethernet, 'sudo ifdown wlan0' command to shut down the wireless, and re-established my SSH remote session over ethernet. Perhaps due to my configuration, I needed to issue the following two commands to re-establish my internet connection (local network link was unaffected). 

Code:

sudo ifconfig eth0 192.168.0.54 netmask 255.255.255.0 broadcast 192.168.0.255
sudo ip route add default via 192.168.0.1

Code:

I have seem a claimed speak spike of about 51MB/s, but you can see the highest average was 26.9 MB/s
