e1000 driver intel 82574L non-responsive and high ping times
Hi,
I am working with a Concurrent Technologies TP 702/38x CompactPCI board
with an intel core i7 and two onboard nics using a Intel 82577LM and
82574L ethernet controller, both of which use the devnp-e1000.so driver.
The 82577LM controller works fine and does not have any issues.
The 82574L controller has very high ping times >1 second when pinging
another system. In looking into the issue with wireshark on another
machine it would appear that there is an issue with the RX interface.
There are occations when the 82574L nic is accessible but it still has
ping times between 20-40 ms.
The ping time for 82577LM is always 0ms.
In looking at other discussions it would appear that the issue is
interrupt related (see
http://community.qnx.com/sf/discussion/do/listPosts/projects.bsp/discussion.bsp.topc18670).
I have attempted to use other interrupts when starting the driver,
however the nic is totally unresponsive when changed.
I have attached some logs for the network and used the following command
to start the drivers:
io-pkt-v4-hc -de1000 did=0x10ea,vid=0x8086 -de1000
did=0x10d3,vid=0x8086,verbose=4 -ptcpip
The driver version I am using is:
NAME=devnp-e1000.so
DESCRIPTION=Driver for Intel 82544 Gigabit Ethernet controllers
DATE=2010/07/09-13:46:54-EDT
STATE=stable
HOST=mainbuild
USER=builder
VERSION=6.5.0
TAGID=89
Is there any updated drivers to fix this issue?
Regards,
Elisha
