Introduction:
=============

    The instructions listed below are for linux driver installation. You must
    compile the source code to generate the module velocityget.o (velocity.ko
    in 2.6.x kernel, please remember to replace velocityget.o with
    velocityget.ko in the following sentences if you are using 2.6.x kernel)
    and use insmod command to insert it.

Kernel Supported
================
    This driver supports linux kernel version 2.2.x, 2.4.x and 2.6.x now.

CPU Supported
=============
    This driver supports x86 and AMD64 based linux system.

Installation
============
    Please enter the following commands at the UNIX prompt. Remember, UNIX is
    case sensitive.

    1) Create a temporary directory:
        mkdir /temp

    2) Change to the temporary directory:
        cd /temp

    3) Copy driver (.tgz file) from DOS disk, (mcopy below is one tool in
       mtools, if you didn't install mtools, you can type
       'mount -t msdos /dev/fd0 /mnt' and use 'cp /mnt/velocityget.tgz /temp'
       command to copy the driver to the temporary directory):
        mcopy a:velocityget.tgz .

    4) untar the archive file:

        tar xzvf velocityget.tgz
        cd velocityget

    5) Compile the driver source files and it will generate object file, and
       copy it to correct driver installation path (The installation directory
       is different in different kernel versions. In 2.4.x/2.6.x kernel, the path
       is /lib/modules/KERNEL_VERSION/kernel/drivers/net/, and in 2.2.x kernel,
       the path is /lib/modules/KERNEL_VERSION/net/, the KERNEL_VERSION (see
       above) means the kernel version of your Linux distribution. If you don't
       know your kernel version , please run 'uname -r' command in command
       line. The kernel version will look like '2.2.16', '2.4.2-2smp' etc.) :
        make install

    6) Check configuration file (/etc/modules.conf or /etc/conf.modules or
       /etc/modprobe.conf, it depends on your Linux distribution) for loading
       kernel modules. Make sure the first line below is appeared in the
       configuration file, where # is the interface number (eg: alias eth0
       velocityfet). If you need to set the driver options, below second line
       is an example to set the NIC to 100Mbps fullduplex mode (remember to
       unmark the line if it is put in the configuration file).
        alias eth# velocityget

    7) Reboot now:
        shutdown -r now

    8) Install your driver module (If the driver module is in the wrong place,
       an error message will appear, and say that can't find the driver
       module):
        insmod velocityget.o

    9) Use ifconfig command to assign the IP address, where # is network
       interface number:
        ifconfig eth# <IP>

    10) Check the interface works:
         ping <remote_host_IP>


Remove intermediate files
=========================
    Please enter the following command to remove intermediate files generated
    during the driver compilation:
        make clean


Uninstallation
==============
    Please enter the following command to uninstall your driver:
        make uninstall


Bind the driver into kernel
===========================
    In some applications (e.g. embedded OS), driver should be bound into the
    kernel. The module installation/uninstallation describled in the above
    sections are not appropriate. Below is the steps for binding driver in
    kernel 2.4.x as an example:

    1) Create a temporary directory:
        mkdir /temp

    2) Change to the temporary directory:
        cd /temp

    3) Copy driver (velocityget.tgz) from DOS disk, (mcopy below is one tool
       in mtools, if you didn't install mtools, you can type
       'mount -t msdos /dev/fd0 /mnt' and use 'cp /mnt/velocityget.tgz /temp'
       command to copy the driver to the temporary directory):
        mcopy a:velocityget.tgz .

    4) untar the archive file:
        tar xzvf velocityget.tgz

    5) Change to the kernel source directory:
        cd /usr/src/<kernel source>/driver/net

    6) Create a directory for Velocity family adapter driver and change to it:
        mkdir velocityget
        cd velocityget

    7) Copy driver source form temporary directory to it:
        cp /temp/velocityget/* .

    8) Replace the default Makefile with new Makefile with below 4 line content
       (the Makefile used for driver binding into kernel is different with
       the default one).
       O_TARGET := velocityget.o
       obj-y    := velocity_main.o velocity_proc.o velocity_wol.o
       obj-m    := $(O_TARGET)
       include  $(TOPDIR)/Rules.make

    9) Add the velocityget information to /usr/src/<kernel source>/drivers/net/Makefile:
       (add the lines with # in the head)
             ...
             ...
        subdir-$(CONFIG_E1000) += e1000
        #subdir-$(CONFIG_VELOCITYGET) += velocityget
             ...
             ...
        ifeq ($(CONFIG_E1000),y)
           obj-y += e1000/e1000.o
        endif
        #ifeq ($(CONFIG_VELOCITYGET),y)
        #   obj-y += velocityget/velocityget.o
        #endif

    10) Add the velocityget information to /usr/src/<kernel source>/drivers/net/Config.in:
        (add the lines with # in the head)
             ...
             ...
        mainmenu_option next_comment
        comment 'Ethernet (1000 Mbit)'
             ...
             ...
        #dep_tristate   '    VIA Netorking Velocity Family Gigabit Ethernet Adapter support' CONFIG_VELOCITYGET $CONFIG_PCI
             ...
             ...
        endmenu

    11) Now, when you use following command, make menuconfig or make xconfig,
        you will find a new device in 'Network device support'->'Ethernet(1000 Mbits)'.
        Its name is 'VIA Netorking Velocity Family Gigabit Ethernet Adapter support'.


Note
====
    1) Make sure the link file /usr/src/linux (or /usr/src/linux-2.4) is linked
       to correctly kernel sources directory (eg: if you run 'uname -r', it
       appears "2.4.2-2", then the link file must be linked to
       /usr/src/linux-2.4.2 directory, or you will fail in compiling),
       and make sure there are kernel header files in /usr/src/linux/include
       directory (or /usr/src/linux-2.4/include), we need kernel header files
       in compling.

    2) If you can't install driver in SUSE Linux using insmod or modprobe
       commands, and error messages appear (see below), please run 'uname -r'
       in command line. And make sure the result of 'uname -r' (eg: 2.4.2-4GB)
       is the same with the definition of UTS_RELEASE in
       /usr/src/linux/include/linux/version.h. If not, please modify the
       definition of UTS_RELEASE in /usr/src/linux/include/linux/version.h.

         velocityget.o: kernel-module version mismatch
             velocityget.o was compiled for kernel version 2.4.2
             while this kernel is version 2.4.2-4GB.

    3) Make sure that your kernel is built with network, fast_ethernet
       and module support. Otherwise, you have to rebuild your kernel (see
       below).
        1. Go to /usr/src/linux (or /usr/src/linux-2.4) directory:
            cd /usr/src/linux
        2: Run 'make menuconfig' or 'make config' in text mode, or 'make
           xconfig' in graphic mode.
        3: Mark the options list above.
        4: Exit and rebuild your kernel:
            make dep;make clean;make bzImage
           The file 'bzImage' will be at /usr/src/linux/arch/i386/boot/bzImage
        5: Modify /etc/lilo.conf.(this file specifies where kernel image is)
        6: Run 'lilo'
        7: Reboot, and select the correct kernel image to boot your system.

    4) You can use the utility (like netconfig, linuxconf) in your Linux
       distribution to set your network parameters(like ip,gateway). These
       parameters will be used at boot time. The following is the demonstration
       to show how to use linuxconf (it's a utitlity in RedHat Linux 6.x) set
       the network paramters.
       1. Run linuxconf:
           linuxconf
       2. Enter setting in the Config/Networking/Client tasks/Basic host information/
          and fill out the following information. Where 'xxx' is the IP address
          what you have.
                    IP address:    xxx.xxx.xxx.xxx
                    Netmask:       255.255.255.xxx
                    Net device:    eth0
                    Kernel module: velocityget

    5) If you can't install driver at boot time.
       If you can install your driver using insmod command, but you can't
       install it at boot time, please check whether the driver is in the
       correct directory (eg: /lib/modules/2.2.XXX/net/), and check the
       /lib/modules/2.2.XXX/modules.dep file, it must include the following
       line:
            /lib/modules/2.2.XXX/net/velocityget.o:

       You can insert this line using depmod command or insert it manually.
       Also, you must consult your Linux distribution installation guide
       and learn how to set the IP address of your network interface and
       up it at boot time.

    6) If you can't compile this driver, and parse error messages appear,
       please make sure your source code text format is right. You must convert
       your source code text format from MS-DOS to UNIX, as show below (see
       Solution 1 and 2).
       Make sure the files in floppy disk are not velocityget.tgz file. They must
       be the source code text files (5 files), velocityget.tgz is not a text file
       , so it can't be converted.

        Solution1:
            If you use mcopy command to copy your driver from floppy disk to
            linux, you can type:
                mcopy -t a:\* .
            then it will convert the format for you.

        Solution2:
            If you use mount command to mount floppy disk to linux, you can
            type:
                mount -t vfat -o conv=t /dev/fd0 /mnt/floppy
            then, when you copy files from /mnt/floppy, these files format will
            be right.

Module Parameter:
=================
The following parameters can be set when we install the driver module. You can
add this parameters when you execute 'insmod' or 'modprobe' command to install
the driver (as below).
    insmod velocityget.o parameter=value1,value2,value3,...
For example, if you have 3 NIC cards, and you want to set the speed_duplex
paramter value of them. You can type the following command to set it.
    insmod velocityget.o speed_duplex=1,2,3
Then, the parameter value of first card will be 1 (100Mbps half duplex mode),
the second card will be 2 (100Mbps full duplex mode), and the third card will
be 3 (10Mbps half duplex mode). Remember, our driver only support 8 cards
parameter setting.

1) speed_duplex
   speed_duplex[] is used for setting the speed and duplex mode of NIC.
   Value:
       0: indicate autonegotiation for both speed and duplex mode (Default).

       2: indicate 100Mbps full duplex mode
       3: indicate 10Mbps half duplex mode
       4: indicate 10Mbps full duplex mode

2) RxDescriptors
   RxDescriptors[] is used for setting the receive descriptor number of NIC.
   The number of RxDescriptors should be divisible by 4. If not, driver will
   truncate the number itself.
   Value:
       64~252

3) TxDescriptors
   RxDescriptors[] is used for setting the transmit descriptor number of NIC.
   Value:

5) VID_setting
   VID_setting[] is used for setting the VLAN ID of NIC.
   Value:
       0: default VID.
       1-4094: other VIDs.

6) txcsum_offload
   csum_offload[] is used for setting the checksum offload ability of NIC.
   Value:
       0: disable
       1: enable (default)

7) flow_control
   flow_control[] is used for setting the flow control ability of NIC. Only
   option 1 (default) set flow control ability according to the auto-negotiation
   result.
   Option 2, 3, 4 and 5 are the forced flow control mode and they don't see the
   auto-negotiation result.
   Value:
       1: hardware deafult - AUTO (Default). Use Hardware default value in ANAR.
       2: enable TX flow control.
       3: enable RX flow control.
       4: enable TX/RX flow control.
       5: disable

8) IP_byte_align
   IP_byte_align[] is used for IP header DWORD byte aligned (For IPVS environment).
   (In some enviroment, the IP header should be DWORD byte aligned,or the packet
   will be droped when we receive it. (eg: IPVS))
   Value:
       0: indicate the IP header won't be DWORD byte aligned (Default).
       1: indicate the IP header will be DWORD byte aligned.

9) ValPktLen
    ValPktLen[] is used for controlling driver to receive or drop
    the frame with invalid layer 2 length.
    Value:
        0: Receive frame with invalid layer 2 length (default).
        1: Drop frame with invalid layer 2 length.

10) wol_opts
    wol_opts[] is used for controlling wake on lan behavior of NIC.
    0: Wake up if recevied a magic packet. (Default)
    2: Wake up if recevied an arp packet.
    4: Wake up if recevied any unicast packet.
    Those value can be sumed up to support more than one option.
