+- D-Link DGE-550T Gigabit Ethernet Adapter.
+- D-Link DGE-550SX Gigabit Ethernet Adapter.
+- D-Link DL2000-based Gigabit Ethernet Adapter.
+
+
+The driver support Linux kernel 2.4.7 later. We had tested it
+on the environments below.
+
+ . Red Hat v6.2 (update kernel to 2.4.7)
+ . Red Hat v7.0 (update kernel to 2.4.7)
+ . Red Hat v7.1 (kernel 2.4.7)
+ . Red Hat v7.2 (kernel 2.4.7-10)
+
+
+Quick Install
+=============
+Install linux driver as following command::
+
+    1. make all
+    2. insmod dl2k.ko
+    3. ifconfig eth0 up 10.xxx.xxx.xxx netmask 255.0.0.0
+			^^^^^^^^^^^^^^^\	    ^^^^^^^^\
+					IP		     NETMASK
+
+Now eth0 should active, you can test it by "ping" or get more information by
+"ifconfig". If tested ok, continue the next step.
+
+4. ``cp dl2k.ko /lib/modules/`uname -r`/kernel/drivers/net``
+5. Add the following line to /etc/modprobe.d/dl2k.conf::
+
+	alias eth0 dl2k
+
+6. Run ``depmod`` to updated module indexes.
+7. Run ``netconfig`` or ``netconf`` to create configuration script ifcfg-eth0
+   located at /etc/sysconfig/network-scripts or create it manually.
+
+   [see - Configuration Script Sample]
+8. Driver will automatically load and configure at next boot time.
+
+Compiling the Driver
+====================
+In Linux, NIC drivers are most commonly configured as loadable modules.
+The approach of building a monolithic kernel has become obsolete. The driver
+can be compiled as part of a monolithic kernel, but is strongly discouraged.
+The remainder of this section assumes the driver is built as a loadable module.
+In the Linux environment, it is a good idea to rebuild the driver from the
+source instead of relying on a precompiled version. This approach provides
+better reliability since a precompiled driver might depend on libraries or
+kernel features that are not present in a given Linux installation.
+
+The 3 files necessary to build Linux device driver are dl2k.c, dl2k.h and
+Makefile. To compile, the Linux installation must include the gcc compiler,
+the kernel source, and the kernel headers. The Linux driver supports Linux
+Kernels 2.4.7. Copy the files to a directory and enter the following command
+to compile and link the driver:
+
+CD-ROM drive
+------------
+
+::
+
+    [root@XXX /] mkdir cdrom
+    [root@XXX /] mount -r -t iso9660 -o conv=auto /dev/cdrom /cdrom
+    [root@XXX /] cd root
+    [root@XXX /root] mkdir dl2k
+    [root@XXX /root] cd dl2k
+    [root@XXX dl2k] cp /cdrom/linux/dl2k.tgz /root/dl2k
+    [root@XXX dl2k] tar xfvz dl2k.tgz
+    [root@XXX dl2k] make all
+
+Floppy disc drive
+-----------------
+
+::
+
+    [root@XXX /] cd root
+    [root@XXX /root] mkdir dl2k
+    [root@XXX /root] cd dl2k
+    [root@XXX dl2k] mcopy a:/linux/dl2k.tgz /root/dl2k
+    [root@XXX dl2k] tar xfvz dl2k.tgz
+    [root@XXX dl2k] make all
+
+Installing the Driver
+=====================
+
+Manual Installation
+-------------------
+
+  Once the driver has been compiled, it must be loaded, enabled, and bound
+  to a protocol stack in order to establish network connectivity. To load a
+  module enter the command::
+
+    insmod dl2k.o
+
+  or::
+
+    insmod dl2k.o <optional parameter>	; add parameter
+
+---------------------------------------------------------
+
+  example::
+
+    insmod dl2k.o media=100mbps_hd
+
+   or::
+
+    insmod dl2k.o media=3
+
+   or::
+
+    insmod dl2k.o media=3,2	; for 2 cards
+
+---------------------------------------------------------
+
+  Please reference the list of the command line parameters supported by
+  the Linux device driver below.
+
+  The insmod command only loads the driver and gives it a name of the form
+  eth0, eth1, etc. To bring the NIC into an operational state,
+  it is necessary to issue the following command::
+
+    ifconfig eth0 up
+
+  Finally, to bind the driver to the active protocol (e.g., TCP/IP with
+  Linux), enter the following command::
+
+    ifup eth0
+
+  Note that this is meaningful only if the system can find a configuration
+  script that contains the necessary network information. A sample will be
+  given in the next paragraph.
+
+  The commands to unload a driver are as follows::
+
+    ifdown eth0
+    ifconfig eth0 down
+    rmmod dl2k.o
+
+  The following are the commands to list the currently loaded modules and
+  to see the current network configuration::
+
+    lsmod
+    ifconfig
+
+
+Automated Installation
+----------------------
+  This section describes how to install the driver such that it is
+  automatically loaded and configured at boot time. The following description
+  is based on a Red Hat 6.0/7.0 distribution, but it can easily be ported to
+  other distributions as well.
+
+Red Hat v6.x/v7.x
+-----------------
+  1. Copy dl2k.o to the network modules directory, typically
+     /lib/modules/2.x.x-xx/net or /lib/modules/2.x.x/kernel/drivers/net.
+  2. Locate the boot module configuration file, most commonly in the
+     /etc/modprobe.d/ directory. Add the following lines::
+
+	alias ethx dl2k
+	options dl2k <optional parameters>
+
+     where ethx will be eth0 if the NIC is the only ethernet adapter, eth1 if
+     one other ethernet adapter is installed, etc. Refer to the table in the
+     previous section for the list of optional parameters.
+  3. Locate the network configuration scripts, normally the
+     /etc/sysconfig/network-scripts directory, and create a configuration
+     script named ifcfg-ethx that contains network information.
+  4. Note that for most Linux distributions, Red Hat included, a configuration
+     utility with a graphical user interface is provided to perform steps 2
+     and 3 above.
+
+
+Parameter Description
+=====================
+You can install this driver without any additional parameter. However, if you
+are going to have extensive functions then it is necessary to set extra
+parameter. Below is a list of the command line parameters supported by the
+Linux device
+driver.
+
+
+===============================   ==============================================
+mtu=packet_size			  Specifies the maximum packet size. default
+				  is 1500.
+
+media=media_type		  Specifies the media type the NIC operates at.
+				  autosense	Autosensing active media.
+
+				  ===========	=========================
+				  10mbps_hd	10Mbps half duplex.
+				  10mbps_fd	10Mbps full duplex.
+				  100mbps_hd	100Mbps half duplex.
+				  100mbps_fd	100Mbps full duplex.
+				  1000mbps_fd	1000Mbps full duplex.
+				  1000mbps_hd	1000Mbps half duplex.
+				  0		Autosensing active media.
+				  1		10Mbps half duplex.
+				  2		10Mbps full duplex.
+				  3		100Mbps half duplex.
+				  4		100Mbps full duplex.
+				  5          	1000Mbps half duplex.
+				  6          	1000Mbps full duplex.
+				  ===========	=========================
+
+				  By default, the NIC operates at autosense.
+				  1000mbps_fd and 1000mbps_hd types are only
+				  available for fiber adapter.
+
+vlan=n				  Specifies the VLAN ID. If vlan=0, the
+				  Virtual Local Area Network (VLAN) function is
+				  disable.
+
+jumbo=[0|1]			  Specifies the jumbo frame support. If jumbo=1,
+				  the NIC accept jumbo frames. By default, this
+				  function is disabled.
+				  Jumbo frame usually improve the performance
+				  int gigabit.
+				  This feature need jumbo frame compatible
+				  remote.
+
+rx_coalesce=m			  Number of rx frame handled each interrupt.
+rx_timeout=n			  Rx DMA wait time for an interrupt.
+				  If set rx_coalesce > 0, hardware only assert
+				  an interrupt for m frames. Hardware won't
+				  assert rx interrupt until m frames received or
+				  reach timeout of n * 640 nano seconds.
+				  Set proper rx_coalesce and rx_timeout can
+				  reduce congestion collapse and overload which
+				  has been a bottleneck for high speed network.
+
+				  For example, rx_coalesce=10 rx_timeout=800.
+				  that is, hardware assert only 1 interrupt
+				  for 10 frames received or timeout of 512 us.
+
+tx_coalesce=n			  Number of tx frame handled each interrupt.
+				  Set n > 1 can reduce the interrupts
+				  congestion usually lower performance of
+				  high speed network card. Default is 16.
+
+tx_flow=[1|0]			  Specifies the Tx flow control. If tx_flow=0,
+				  the Tx flow control disable else driver
+				  autodetect.
+rx_flow=[1|0]			  Specifies the Rx flow control. If rx_flow=0,
+				  the Rx flow control enable else driver
+				  autodetect.
+===============================   ==============================================
+
+
+Configuration Script Sample
+===========================
+Here is a sample of a simple configuration script::
+
+    DEVICE=eth0
+    USERCTL=no
+    ONBOOT=yes
+    POOTPROTO=none
+    BROADCAST=207.200.5.255
+    NETWORK=207.200.5.0
+    NETMASK=255.255.255.0
+    IPADDR=207.200.5.2
+
+
+Troubleshooting
+===============
+Q1. Source files contain ^ M behind every line.
+
+    Make sure all files are Unix file format (no LF). Try the following
+    shell command to convert files::
+
+	cat dl2k.c | col -b > dl2k.tmp
+	mv dl2k.tmp dl2k.c
+
+    OR::
+
+	cat dl2k.c | tr -d "\r" > dl2k.tmp
+	mv dl2k.tmp dl2k.c
+
+Q2: Could not find header files (``*.h``)?
+
+    To compile the driver, you need kernel header files. After
+    installing the kernel source, the header files are usually located in
+    /usr/src/linux/include, which is the default include directory configured
+    in Makefile. For some distributions, there is a copy of header files in
+    /usr/src/include/linux and /usr/src/include/asm, that you can change the
+    INCLUDEDIR in Makefile to /usr/include without installing kernel source.
+
+    Note that RH 7.0 didn't provide correct header files in /usr/include,
+    including those files will make a wrong version driver.
