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. + |
