<DIV>Hi Rick,<BR></DIV>
<DIV> I use
netperf test on ARM board ,the network work module is 10M half/full duplex. but
test </DIV>
<DIV> </DIV>
<DIV>some times appear the following phenomenon:</DIV>
<DIV> </DIV>
<DIV>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<BR><STRONG>NETDEV WATCHDOG: eth0: transmit timed
out<BR>netperf: receive_response: no response received. errno 0 counter
0</STRONG></DIV>
<DIV>....................</DIV>
<DIV>The TCP_STREAM result:<BR><STRONG>establish control: are you sure there is
a netserver listening on 192.168.1.2 at port 12865?<BR>establish_control could
not establish the control connection from 0.0.0.0 port 0 address family
AF_UN<BR>SPEC to 192.168.1.2 port 12865 address family
