Compiling the Driver
====================
- In Linux, NIC drivers are most commonly configured as loadable modules.
+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.

Installing the Driver
=====================
- Manual Installation
- -------------------
+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:
+ module enter the command::
+
+ insmod dl2k.o
+
+ or::
+
+ insmod dl2k.o <optional parameter> ; add parameter
- insmod dl2k.o
+---------------------------------------------------------
- or
+ example::
- insmod dl2k.o <optional parameter> ; add parameter
+ insmod dl2k.o media=100mbps_hd
- ===============================================================
- example: insmod dl2k.o media=100mbps_hd
- or insmod dl2k.o media=3
- or insmod dl2k.o media=3,2 ; for 2 cards

+ insmod dl2k.o media=3

+ 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:
+ 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.

+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
- -----------------
+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:
+ /etc/modprobe.d/ directory. Add the following lines::
- alias ethx dl2k
- options dl2k <optional parameters>
+ 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
Linux device
driver.

+ To compile the driver, you need kernel header files. After
installing the kernel source, the header files are usually located in

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.
