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
