Untar/unzip the archive: - - tar xvfz 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 in system directory: - - make install - - c. If you want the driver to load automatically when the system is booted: - - 1.

Similarly, - turn off polling mode by setting the variable to 0: - - sysctl kern.polling.enable=1 - - - NOTES: DEVICE POLLING is only valid for non-SMP kernels. - - The driver has to be built into the kernel for DEVICE POLLING to be - enabled in the driver. - - -Known Limitations -================= - - There are known performance issues with this driver when running UDP traffic - with Jumbo Frames. Intel recommends not using Jumbo Frames for UDP traffic. - - - 82541/82547 can't link or is slow to link with some link partners - ----------------------------------------------------------------- - - There is a known compatibility issue with 82541/82547 and some switches - where link will not be established, or will be slow to establish. In - particular, these switches are known to be incompatible with 82541/82547: - - Planex FXG-08TE - I-O Data ETG-SH8 - - To workaround the issue, the driver can be compiled with an override of the - PHY's master/slave setting. Forcing master or forcing slave mode will - improve time-to-link. - - Edit ./em.x.x.x/src/if_em.h to remove the #define EM_MASTER_SLAVE - from within the comments. - - /* #define EM_MASTER_SLAVE 2 */ - #define EM_MASTER_SLAVE 2 - - Use one of the following options. - 0 = Hardware default - 1 = Master mode - 2 = Slave mode - 3 = Auto master/slave - - Recompile the module (refer to step 3 above) - a. To compile the module - - cd em-x.x.x - make clean - make - - b.

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.
