All hardware requirements listed -apply to use with FreeBSD. - - -Identifying Your Adapter -======================== - -For information on how to identify your adapter, go to the Adapter & -Driver ID Guide at: - -http://support.intel.com/support/network/sb/cs-012904.htm - - -For the latest Intel network drivers for FreeBSD, see: - -http://downloadfinder.intel.com/scripts-df-external/support_intel.aspx - - -NOTE: Mobile adapters are not fully supported. -NOTE: The Intel(R) 82562v 10/100 Network Connection only provides 10/100 -support. - -Building and Installation -========================= - -NOTE: The driver can be installed as a dynamic loadable kernel module or - compiled into the kernel. You must have kernel sources installed in - order to compile the driver module. - -In the instructions below, x.x.x is the driver version as indicated in the -name of the driver tar file. - -1. Move the base driver tar file to the directory of your choice. For - example, use /home/username/em or /usr/local/src/em. - -2. Untar/unzip the archive: - - tar xzvf em-x.x.x.tar.gz - - This will create an em-x.x.x directory. - -3. To create a loadable module, perform the following steps. - NOTE: To compile the driver into the kernel, go directly to step 4. - - a. To compile the module - - cd em-x.x.x - make - - b. To install the compiled module to the system directory: - - make install - - c. If you want the driver to load automatically when the system is booted: - - 1. Edit /boot/loader.conf, and add the following line: - - if_em_load="YES" - -4. To compile the driver into the kernel, enter: - - cd em-x.x.x/src - cp *.[ch] /usr/src/sys/dev/em - - Edit the kernel configuration file (i.e., GENERIC or MYKERNEL) in - /usr/src/sys/i386/conf, and ensure the following line is present: - - device em - - Compile and install the kernel. The system must be rebooted for the - kernel updates to take effect. For additional information on compiling - the kernel, consult the FreeBSD operating system documentation. - -5. To assign an IP address to the interface, enter the following: - - ifconfig em - -6. Verify that the interface works. Enter the following, where - is the IP address for another machine on the same subnet as the interface - that is being tested: - - ping - -7. To configure the IP address to remain after reboot, edit /etc/rc.conf, - and create the appropriate ifconfig_ementry: - - ifconfig_em="" - - Example usage: - - ifconfig_em0="inet 192.168.10.1 netmask 255.255.255.0" - - NOTE: For assistance, see the ifconfig man page. - - -Speed and Duplex Configuration -============================== - -By default, the adapter auto-negotiates the speed and duplex of the -connection. If there is a specific need, the ifconfig utility can be used to -configure the speed and duplex settings on the adapter. Example usage: - - ifconfig em media 100baseTX mediaopt - full-duplex - - NOTE: Only use mediaopt to set the driver to full-duplex. If mediaopt is - not specified and you are not running at gigabit speed, the driver - defaults to half-duplex. - -If the interface is currently forced to 100 full duplex, in order to change -to half duplex you must use this command: - - ifconfig em media 100baseTX -mediaopt - full-duplex - - -This driver supports the following media type options: - - autoselect - Enables auto-negotiation for speed and duplex. - - 10baseT/UTP - Sets speed to 10 Mbps. Use the ifconfig mediaopt - option to select full-duplex mode. - - 100baseTX - Sets speed to 100 Mbps. Use the ifconfig mediaopt - option to select full-duplex mode. - - 1000baseTX - Sets speed to 1000 Mbps. In this case, the driver - supports only full-duplex mode. - - 1000baseSX - Sets speed to 1000 Mbps. In this case, the driver - supports only full-duplex mode. - -For more information on the ifconfig utility, see the ifconfig man page. - - -Additional Configurations -========================= - -The driver supports Transmit/Receive Checksum Offload and Jumbo Frames on -all but the 82542-based adapters. For specific adapters, refer to the -Identifying Your Adapter section. - - Jumbo Frames - ------------ - To enable Jumbo Frames, use the ifconfig utility to set the Maximum - Transport Unit (MTU) frame size above its default of 1500 bytes. - - The Jumbo Frames MTU range for Intel Adapters is 1500 to 16110. To modify - the setting, enter the following: - - ifconfig em mtu 9000 - - To confirm the MTU used between two specific devices, use: - - route get - - Notes: - - - Only enable Jumbo Frames if your network infrastructure supports them. - - - To enable Jumbo Frames, increase the MTU size on the interface beyond - 1500. - - - The Jumbo Frames setting on the switch must be set to at least 22 bytes - larger than that of the MTU. - - - The maximum MTU setting for Jumbo Frames is 16110. This value coincides - with the maximum Jumbo Frames size of 16128. - - - Some Intel gigabit adapters that support Jumbo Frames have a frame size - limit of 9238 bytes, with a corresponding MTU size limit of 9216 bytes. - The adapters with this limitation are based on the Intel(R) 82571EB, - 82572EI, 82573L, 82566, 82562, and 80003ES2LAN controller. These - correspond to the following product names: - Intel(R) PRO/1000 PT Server Adapter - Intel(R) PRO/1000 PT Desktop Adapter - Intel(R) PRO/1000 PT Network Connection - Intel(R) PRO/1000 PT Dual Port Server Adapter - Intel(R) PRO/1000 PT Dual Port Network Connection - Intel(R) PRO/1000 PT Quad Port Server Adapter - Intel(R) PRO/1000 PF Quad Port Server Adapter - Intel(R) PRO/1000 PF Server Adapter - Intel(R) PRO/1000 PF Network Connection - Intel(R) PRO/1000 PF Dual Port Server Adapter - Intel(R) PRO/1000 PB Server Connection - Intel(R) PRO/1000 PL Network Connection - Intel(R) PRO/1000 EB Network Connection with I/O Acceleration - Intel(R) PRO/1000 EB Backplane Connection with I/O Acceleration - Intel(R) 82566DM-2 Gigabit Network Connection - - - Adapters based on the Intel(R) 82542 and 82573V/E controller do not - support Jumbo Frames. These correspond to the following product names: - Intel(R) PRO/1000 Gigabit Server Adapter - Intel(R) PRO/1000 PM Network Connection - - - Using Jumbo Frames at 10 or 100 Mbps may result in poor performance or - loss of link. - - - The following adapters do not support Jumbo Frames: - Intel(R) 82562V 10/100 Network Connection - Intel(R) 82566DM Gigabit Network Connection - Intel(R) 82566DC Gigabit Network Connection - Intel(R) 82566MM Gigabit Network Connection - Intel(R) 82566MC Gigabit Network Connection - Intel(R) 82562GT 10/100 Network Connection - Intel(R) 82562G 10/100 Network Connection - Intel(R) 82566DC-2 Gigabit Network Connection - Intel(R) 82562V-2 10/100 Network Connection - Intel(R) 82562G-2 10/100 Network Connection - Intel(R) 82562GT-2 10/100 Network Connection - - VLANs - ----- - To create a new VLAN interface: - - ifconfig create - - To associate the VLAN interface with a physical interface and - assign a VLAN ID, IP address, and netmask: - - ifconfig netmask vlan - vlandev - - Example: - - ifconfig vlan10 10.0.0.1 netmask 255.255.255.0 vlan 10 vlandev em0 - - In this example, all packets will be marked on egress with 802.1Q VLAN - tags, specifying a VLAN ID of 10. - - To remove a VLAN interface: - - Intel Network Connection ifconfig destroy - - - Polling - ------- - - To enable polling in the driver, add the following options to the kernel - configuration, and then recompile the kernel: - - options DEVICE_POLLING - options HZ=1000 - - At runtime use: - ifconfig emX polling (to turn polling on) - and: - ifconfig emX -polling (to turn it off) - - - Checksum Offload - ---------------- - Checksum offloading is not supported on 82542 Gigabit adapters. - - Checksum offloading supports both TCP and UDP packets and is - supported for both transmit and receive. - - Checksum offloading can be enabled or disabled using ifconfig. - Both transmit and receive offloading will be either enabled or - disabled together. You cannot enable/disable one without the other. - - To enable checksum offloading: - - ifconfig rxcsum - - To disable checksum offloading: - - ifconfig -rxcsum - - To confirm the current setting: - - ifconfig - - Look for the presence or absence of the following line: - - options=3 - - See the ifconfig man page for further information. - - - TSO - --- - The FreeBSD driver offers support for TSO (TCP Segmentation Offload). - - You can enable/disable it in two ways/places: - - - sysctl net.inet.tcp.tso=0 (or 1 to enable it) - - Doing this disables TSO in the stack and will affect all adapters. - - - ifconfig emX -tso - - Doing this will disable TSO only for this adapter. - - To enable: - - - ifconfig emX tso - - NOTES: By default only PCI-Express adapters are ENABLED to do TSO. Others - can be enabled by the user at their own risk - TSO is not supported on 82547 and 82544-based adapters, as well as older adapters. - - -Known Limitations -================= - - Detected Tx Unit Hang in Quad Port Adapters - ------------------------------------------- - - In some cases ports 3 and 4 wont pass traffic. Ports 1 and 2 don't show - any errors and will pass traffic. - - This issue MAY be resolved by updating to the latest BIOS. You can - check your system's BIOS by downloading the Linux Firmware Developer Kit - that can be obtained at http://www.linuxfirmwarekit.org/ - - - There are known performance issues with this driver when running UDP traffic - with Jumbo Frames. - ---------------------------------------------------------------------------- - - 82541/82547 can't link or is slow to link with some link partners - ----------------------------------------------------------------- - - There is a known compatibility issue where time to link is slow or link is not - established between 82541/82547 controllers and some switches. Known switches - include: - Planex FXG-08TE - I-O Data ETG-SH8 - Netgear GS105v3 - - The driver can be compiled with the following changes: - - Edit ./em.x.x.x/src/if_em.h to change the #define EM_MASTER_SLAVE - For example, change from: - - #define EM_MASTER_SLAVE e1000_ms_hw_default - to: - #define EM_MASTER_SLAVE 2 - - Use one of the following options: - 1 = Master mode - 2 = Slave mode - 3 = Auto master/slave - Setting 2 is recommended. - - Recompile the module: - a. To compile the module - cd em-x.x.x - make clean - make - - b.
