using multiple Intel Pro 1000 network cards
Hi Robert,
We have a customer who is trying to run three network cards simultaneously.
Has anyone tried to do this? Is there anything that we need to be careful
with in trying to set this up?
I have included the complete email from our distributor, who is helping our
customer with this issue.
Thanks!!
- Ed

Ed/Larry,
How should we proceed on the issue below?
They are evaluating QNX and have some performance challenges with the
existing TCP/IP stack with Gigabit camera and other problems with the new
TCP/IP stack in beta.
They have a small fanless computer with two onboard network cards Intel Pro
1000 PL and one extra PCI express Intel Pro 1000 PT. Our goal is to connect
two GigaBit cameras to this computer.
When they start the network driver with: io-net -di82544 -ptcpip it will
(according to ifconfig) detect the two onbard cards.
They are now able to connect to a camera but the CPU load is very high
(around 50%) which means that when they connect the second camera and add
the image processing the load will probably be too high.
They have also downloaded the io-pkt package which claims to be both much
more efficient and also can handle jumboframes. When they now start the
driver with "io-pkt-v4 -di82544 -ptcpip" it detects all three network cards
but only the extra card
will work. Ifconfig is not able to detect the mac-address of the two onboard
cards (it reports ff:ff:ff:ff:ff:ff:ff for those) which we guess is related
to the problem. They are able to "ping" the camera though, even when it is
connected to
the cards with ff:ff:ff:ff:ff:ff mac address, but no other communication
works

RE: using multiple Intel Pro 1000 network cards
Looking at your pci output, I see
You have two different types of i82544
cards (did 0x10b9 and 0x109a). I
wonder if the driver is not seeing
all of them (esp the 10b9?)
A newer driver might also be an idea ...
Because of all the new and different
Chipsets supported by this driver (over
60 hardware variants, last time I checked)
it's getting updated frequently.

RE: using multiple Intel Pro 1000 network cards
Hi Ed:
We've got a bit of a driver dilemma here. The GA io-net driver
likely isn't detecting one of the cards and the io-pkt driver needs some
updates to support reading from the EEPROMs of some newer cards (which is
why the MAC addresses are out of whack). So what I would propose is this:
In this forum post,
http://community.qnx.com/sf/discussion/do/listPosts/projects.bsp/discussion.
bsp.topc2188?pageSize=-1#post5716
Hugh attached an "experimental" build of the i82544 driver for io-net. (See
the second posting). I'd give this one a shot and see if that clears up the
io-net problem.
For io-pkt, I'm in the process of adding the NetBSD wm build directory to
the build so that you can try it out. This driver isn't going to be a
supported driver, but it will let you at least kick the tires with the newer
cards until we get to updating our native driver. That should be in some
time today or Monday.
Robert.

Re: RE: using multiple Intel Pro 1000 network cards
Hello guys,
we are the customer who are evaluating QNX with the described problem. I made an update and installed yesterdays version
of io-pkt, and started it with
io-pkt-v4 -di82544 -ptcpip
However, I still only get ff:ff:ff:ff:ff:ff:ff for the internal network cards. Was there any fix made to solve the
problem with reading from the EEPROM or is it still on the todo list? In the meantime, we can use io-net, which now
detects all three network cards with the experimental driver.
Best regards,
Roland

Two thoughts:
1) Rob has fixed the eeprom code in the io-pkt
i82544 driver - not sure if he's checked it in
yet. I think me and Sean were supposed to code
review it, and I dunno about Sean, but I haven't
yet - sorry! :-(
2) you can use the io-net driver with io-pkt -
just specify the full path to the io-net driver,
and io-pkt will automatically start the shim for
you. There are actually 3 different drivers for
each of the i82544 and speedo for io-pkt.

Code review is in progress. It should hopefully be in soon.

RE: RE: using multiple Intel Pro 1000 network cards
How about giving this x86 version try. It's "highly experimental" at this
point.
Just as a side note, you should try playing with the irq_thresh option to
the driver. It will GREATLY reduce your CPU usage. The optimal value will
depend upon how fast your CPU is. I use a value of 8000 on a 2.2GHz x86.
On another note, you can also try the NetBSD wm driver which has the
advantage of including Transmit Segmentation Offload which can give you
markedly reduced CPU utilization for transmission of large amounts of data.
Robert.

Thanks again,
yes both the older experimental and this one worked fine with io-pkt. I will see how io-thresh affects the CPU load. Do
you have any planned official release of the driver and io-pkt soon (except "2008" that is stated in the project roadmap
:) )?

RE: RE: RE: using multiple Intel Pro 1000 network cards
Hi Roland:
That's good to know! Now all I need to do is get the code finalized
and checked in. You'll find that the irq_thresh (which is the total number
of interrupts per second that the card will produce) can make quite a
difference to CPU usage. You'll find that, at some point, there's a
trade-off between raw throughput and CPU, so you adjust the number up until
you reach that point and that's where you leave it. This mainly affects
receive performance although there will also be a smaller affect on transmit
for TCP (since ACK reception determines what happens with the TCP window).
In terms of release date, we've been re-aligning the release to match up
with a major release of our whole product in the fall (io-pkt is
incorporated in this release as opposed to being a standlone install).
We're still trying to dot i's and cross t's on that one but should have more
information shortly.
Robert.
