[netperf-talk] When test some times the network card download

[liuhu]

Hi Rick,

            I use netperf test on ARM board ,the network work module is 10M half/full duplex. but test 

some times appear the following  phenomenon:

TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.1.2 (192.168.1.2) port 0 AF_INET
NETDEV WATCHDOG: eth0: transmit timed out
netperf: receive_response: no response received. errno 0 counter 0
....................
The TCP_STREAM result:
establish control: are you sure there is a netserver listening on 192.168.1.2 at port 12865?
establish_control could not establish the control connection from 0.0.0.0 port 0 address family AF_UN
SPEC to 192.168.1.2 port 12865 address family AF_UNSPEC
eth0      Link encap:Ethernet  HWaddr 00:00:EB:FA:02:13  
          inet addr:192.168.1.7  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:60330 errors:26929 dropped:0 overruns:26929 frame:0
          TX packets:1845293 errors:446 dropped:0 overruns:4 carrier:442
          collisions:0 txqueuelen:1000 
          RX bytes:4116539 (3.9 Mb)  TX bytes:2755830578 (2628.1 Mb)
          Interrupt:4 Base address:0xe300 DMA chan:ff 

lo        Link encap:Local Loopback  
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)


then the follow test can not go on.

Why the network card eth0 transmit timed out? 

Why the netperf receive_response?

It's my ARM board driver question or another ?


Best Regards
