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. - |
