Title: Network performance

Hi everybody

My board has ethernet problems in 1000/full mode , iperf output indicates 1,5mbps in tcp. When i force 100/full i got 90mbps in iperf. Résults are the same under linux and android

Is it a kernel bug ??

Thx you

Hi Zhansb,

here is the full boot log http://pastebin.com/KhHqCQwb

Then when i put the wire in 100Mbps switch

[ 326.247106] libphy: stmmac-0:01 - Link is Down

[ 336.087163] stmmc_pltfr_fix_mac_speed: fix speed to 100

[ 336.087181] stmmc_pltfr_fix_mac_speed: fix speed for RGMII

[ 336.087190] libphy: stmmac-0:01 - Link is Up - 100/Full

I got packet loss when i ping a computer on my network.

ping 192.168.1.1

I'm an IT Tech so i got all basic verifications, i changed switch and wires. My network is ok with other computers and devices.

Thx for your help

make sure your network cable and router support 1000M?

if they are correct ,the log will be like this:

[  453.385496] stmmc_pltfr_fix_mac_speed: fix speed to 1000
[  453.385735] stmmc_pltfr_fix_mac_speed: fix speed for RGMII
[  453.385844] libphy: stmmac-0:01 - Link is Up - 1000/Full

Hi,

The 1000/full logs are in the pastebin Line 1135.

My network is giga ok , working good with computer and PS3 and synology ds415

Please could you give me a réal way to Check ?? I tryed at office i got same matter, is my board défective ???

try connect device and computer directly .
set a static ip for device . make sure the same network segment and under the 1000/Full environment
try to ping your computer again .check the Packet loss rate and iperf your computer ip again.

It really think there is a problem and that's not located on my network

I 'll try to compile a 3.17 kernel to see if there are changes

Thx
