    Default Cannot install 3 quad port nics at the same time

    I have problem installing 3 Nics at the same time. Only two cards can be installed.
    lspci shows all 12 ports, but dmesg says that the limit is 8 for some reason!?
    BTW, I tried several linux distros so this is not linked to specific os.

    this is the output

    lspci

    In other words, all 12 port are here and the NICs have their drivers installe din 2.6x kernel.


    but, ifconfig -a shows only up to eth8 (eth0 is integarted on mobo i use for internet connection).

    Why is it giving last 4 lines ?

    Thx for any input.

    Default Re: Cannot install 3 quad port nics at the same time

    Looks like the driver only supports a max of 8 instances. A read of the source would confirm or refute this.

    Later: Ok, here is the part in via-velocity.c:

    Code:
            /* FIXME: this driver, like almost all other ethernet drivers,
             * can support more than MAX_UNITS.
             */
            if (velocity_nics >= MAX_UNITS) {
                    dev_notice(&pdev->dev, "already found %d NICs.\n",
                               velocity_nics);
                    return -ENODEV;
            }
    You would have to recompile via-velocity.c, editing MAX_UNITS in via-velocity.h.

    Default Re: Cannot install 3 quad port nics at the same time

    Oh wow, great find. Thank you. I wasn't thinking this might be driver related, as it was suppose to be intergated with 2.6 kernel and should work fine. Well why 8 instances??

    So, i should edit via-velocity.h, and reload the system? I'm not a programmer so i'm not sure how to recompile.

    thx again!
    btw i posted this on several forums and nobody could even give a hint on this!

    Ok, i can't seem to find via-velocity.h,c or anything like that in ubuntu.

    What file should i be looking for? help

    Default Re: Cannot install 3 quad port nics at the same time

    You'll need to install the kernel source package, I think it's linux-source on Ubuntu and kernel-source on openSUSE. Then you need to edit via-velocity.h and recompile that kernel module. I don't have any instructions for you off the top of my head, I would have to search for it myself. Hopefully you should be able to compile just that module and replace the stock via-velocity.ko in /lib/modules. You will also need gcc and make packages installed. Unfortunately you have to do this every time the kernel is updated.

    As for why 8, it looks like the driver was written by VIA people and somebody made the assumption that nobody would install more than 8 NICs of this type, for a maximum aggregate bandwidth of 8Gb/s. But you proved them wrong. So I would also file an enhancement request at bugzilla.novell.com (or launchpad for Ubuntu) asking for this limit to be raised in the upstream kernel sources. They will relay the request upstream and hopefully this will be changed in later releases for everybody.

    Any chance for a step by step configuration with commands?
    I can't seem to make it work

    Default Re: Cannot install 3 quad port nics at the same time

    The file you want to modify is velocity_cfg.h. In line 64, change the max units, save and then run the makefile (sh ./makefile) and see what happens.
    (Follow the instructions in the .txt files)

    I can't find the file.
    I downloaded linux-headers from synaptic package, but
    find / -iname "velocity_cfg.h" doesn't show anything.

    there is velocity.h in /usr/src/linux-headers-2.6.28.11-generic/include/config/via/velocity.h

    but the file is empty. please advice.

    Download the driver from: VIA Drivers Download - VIA Technologies, Inc.
    Opensuse 11.x isn't on the list, but choose the opensuse one.
