+Overview
+========
+
+This file describes the FreeBSD* driver for Intel® Ethernet. This driver has
+been developed for use with FreeBSD, Release 7.x.
+
+For questions related to hardware requirements, refer to the documentation
+supplied with your Gigabit adapter. 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/go/network/adapter/proidguide.htm
+
+
+For the latest Intel network drivers for FreeBSD, see:
+
+http://support.intel.com/support/go/network/adapter/home.htm
+
+
+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: This driver is only supported as a loadable module at this time.
+
+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.
+
+ 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 assign an IP address to the interface, enter the following:
+
+ ifconfig emX <IP_address>
+
+5. Verify that the interface works. Enter the following, where <IP_address>
+ is the IP address for another machine on the same subnet as the interface
+ that is being tested:
+
+ ping <IP_address>
+
+6. To configure the IP address to remain after reboot, edit /etc/rc.conf,
+ and create the appropriate ifconfig_em<interface_num> entry:
+
+ ifconfig_em<interface_num>="<ifconfig_settings>"
+
+ 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 emX <IP_address> 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 emX <IP_address> 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 emX <hostname or IP address> mtu 9000
+
+ To confirm the MTU used between two specific devices, use:
+
+ route get <destination_IP_address>
+
+ 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
+ Intel(R) 82574L Gigabit Network Connection
+ Intel(R) Gigabit CT Desktop Adapter
+ Intel(R) 82567LM-4 Gigabit Network Connection
+ Intel(R) 82567LM-3 Gigabit Network Connection
+ Intel(R) 82567LF-3 Gigabit Network Connection
+
+ - Using Jumbo Frames at 10 or 100 Mbps may result in poor performance or
+ loss of link.
+
+ - The following adapters limit Jumbo Frames sized packets to a maximum of
+ 4088 bytes:
+ Intel(R) 82578DM Gigabit Network Connection
+
+ - The following adapters do not support Jumbo Frames:
+ Intel(R) PRO/1000 Gigabit Server Adapter
+ Intel(R) PRO/1000 PM Network Connection
+ 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
+ Intel(R) 82578DC Gigabit Network Connection
+ Intel(R) 82567V-3 Gigabit Network Connection
+
+ VLANs
+ -----
+ To create a new VLAN interface:
+
+ ifconfig <vlan_name> create
+
+ To associate the VLAN interface with a physical interface and
+ assign a VLAN ID, IP address, and netmask:
+
+ ifconfig <vlan_name> <ip_address> netmask <subnet_mask> vlan
+ <vlan_id> vlandev <physical_interface>
+
+ 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 <vlan_name> 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 emX rxcsum
+
+ To disable checksum offloading:
+
+ ifconfig emX -rxcsum
+
+ To confirm the current setting:
+
+ ifconfig emX
+
+ Look for the presence or absence of the following line:
+
+ options=3 <RXCSUM,TXCSUM>
+
+ 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.
+
+ Timesync
+ --------
+ The FreeBSD driver offers support for Timesync with 82574L, 82567LM, and
+ 82567LF-based network connections. Timesync is used to keep applications
+ in sync by adding very precise timestamps to both outbound and inbound
+ packets.
+
+ Timesync is off by default. To enable, edit the makefile by uncommenting the
+ line:
+
+ #CFLAGS +=-DEM_TIMESYNC
+
+ This will compile support into the driver. When the driver loads on
+ supported hardware the feature will initialize.
+
+ MSI-X
+ -----
+ The FreeBSD driver offers MSIX support with 82574L-based network connections.
+ 82574L-based network connections will use MSI-X by default.
+
+ MSI or MSI-X can be turned off by an entry in /etc/sysctl.conf
+
+ hw.em.enable_msi=0
+
+ Unload and reload the driver.
+
+
+Known Limitations
+=================
+
+For known hardware and troubleshooting issues, refer to the following website.
+
+ http://support.intel.com/support/go/network/adapter/home.htm
+
+Either select the link for your adapter or perform a search for the adapter
+number. The adapter's page lists many issues. For a complete list of hardware
+issues download your adapter's user guide and read the Release Notes.
+
+ Detected Tx Unit Hang in Quad Port Adapters
+ -------------------------------------------
+
+ In some cases ports 3 and 4 won’t 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
+
+ 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. To install the compiled module in system directory:
+ make install
