Compiler: The difference network bandwidth between DP83TC811R-Q1's specifications and Linux's dmesg

user6065254

Intellectual 390 points

Other Parts Discussed in Thread: DP83TC811R-Q1, DP83TC811EVM

Tool/software: TI C/C++ Compiler

The system information as below:

1. Broad: TDA2EX-17

2. Ethernet PHY: DP83TC811R-Q1

3. Linux System: 4.4.84-00041-geb8fba6-dirty

4. PROCESSOR SDK Version: 3.07

The bandwidth in hardware specifications of DP83TC811R-Q1 is 100 Mbps.

Then I followed this specifications to verify by those steps:

1. Device connect to another one directly.

2. Using the "iperf" software to test the bandwidth. (The one device as server, and the other as client.)

The software shows that the bandwidth between two devices is 91Mbps and the bandwidth anneals to the hardware's specification.

But the system's message(dmesg) shows the ethernet bandwidth is 10 Mbps/Half(cpsw 48484000.ethernet eth0: Link is Up - 10Mbps/Half - flow control off).

So, I have questions about the difference between system's message and hardware's specifications:

(1) Does the hardware's actual bandwidth reach to 100 Mbps?

(2) I guess the system's driver go wrong. How to solve it?

there are two parts to your observation

First is the speed at which the link is negotiated between the peers
1. you can dump the link status by using the ethtool command from Linux console on your board
2. syntax for usage would be #ethttool eth0
3. this will help ascertain whether you have an active link and speed of operation
Second is the throughput as measured by iperf (or similar) - the b/w measured in this case depends on a number of factors, but in general each packet sent on the wire comes with additional overhead(inter-packet gap, preamble etc) Additionally you have packetization overhead of adding L2/L3 headers etc. Hence the throughput measured will always be less than the theoretical b/w possible. Lastly CPU cycles are spent in generating the packet content and hence that could also throttle the throughput. for sufficiently large packet MTU size, you should be able to get close enough especially for 100Mbps link where CPU cycles may not be limiting factor

Can you clarify on the overall goal in terms of performance requirement

Hi,

Thanks for your reply, I want to estimate the system's capability.

I tried the ethtool to observe the link's speed, the tool showed 10 Mbps( same as dmesg ).
Message shows in below:

root@dra7xx-evm:/home# ./ethtool eth0
Settings for eth0:
Supported ports: [ TP AUI BNC MII FIBRE ]
Supported link modes: Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Supported FEC modes: Not reported
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Advertised FEC modes: Not reported
Speed: 10Mb/s
Duplex: Half
Port: MII
PHYAD: 0
Transceiver: external
Auto-negotiation: on
Supports Wake-on: d
Wake-on: d
Current message level: 0x00000000 (0)

Link detected: yes

But I tested the link's speed by using iperf , it showed 91.X Mbps( similar to my last testing result ).
Result shows in below:

root@dra7xx-evm:/home# ./iperf -c 192.168.107.236 -w 16M -t 60 -i 10 -d

[ 5] 0.0-60.0 sec 654 MBytes 91.4 Mbits/sec

So, I'm wondering that:

1. Why makes the different result between system message(dmesg) and software testing?

2. What is the exactly speed about this hardware?

3. Is it a bug to the system's driver? How to fix it?

4. I tried different MTU, but I can't set the value more than 1500(it can set any value below 1500), is it possible to set it up to 9000?

TI__Expert 8250 points

can you confirm if there is only one network interface i.e eth0 and that all traffic is being sent over that interface

i am actually concerned that the link is being negotiated at 10Mb/s , half-duplex. Most modern equipment today support auto-negotiation and will establish link at 100/1000Mbps , full duplex. Can you first review why the link is being established at 10Mbps

can you get dump of the following

#ifconfig
if you have more than one network I/F, dump the routing table with # route -n

Laslty, i am puzzled at how the reported iperf b/w is actually higher than the link speed.

Will need to review the complete data to analyze why this could be

Are there updates on this - is the issue still open. If so, can you revert back with details from my earlier post

Is there any other software to test and verify the actual speed?

TI__Expert 8250 points

Link speed should be reported correctly with #ethtool eth0, but in your case, we seem to negotiate 10Mbps only

Can you confirm if you see this on TI EVM or on a custom board and also share details of what is it connected to

Also, if possible share the complete boot up log

Hi:

1. I have two types of broad ( TDA2-evm, TDA2EX-17 ), the boot up log as attachment.

The TDA2EX-17 broad is my custom broad and using 'DP83TC811EVM broad' to convert ethernet signal from 2-pins PHY to RJ-45.

Then, two devices respectively connect to 1G-switch using the same cable(RJ-45).

2. it seems that the driver is not fully supported for 'DP83TC811R-Q1'. Is there any patch to resolve it?

Thank you.

This does not seem to be related to the ethernet driver but more a link negotiation issue at the PHY level

I am not entirely familiar with the PHY part that you have mentioned above.

What changes did you make for enabling support for the new PHY part

Have you ensured that the PHY boot strap settings are for 100Mbps, full-duplex, auto-negotiation enabled - with this the PHY should link up at 100Mbps without need for SW intervention, you can check at the external switch side if there is a visual LED indication for this
