If the adapter cannot establish link with the link partner +using auto-negotiation, you may need to manually configure the adapter and link +partner to identical settings to establish link and pass packets. This should +only be needed when attempting to link with an older switch that does not +support auto-negotiation or one that has been forced to a specific speed or +duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds +and higher cannot be forced. Use the autonegotiation advertising setting to +manually set devices for 1 Gbps and higher. - autoselect - Enables auto-negotiation for speed and duplex. +Caution: Only experienced network administrators should force speed and duplex +or change autonegotiation advertising manually. The settings at the switch must +always match the adapter settings. Adapter performance may suffer or your +adapter may not operate if you configure the adapter differently from your +switch. - 10baseT/UTP - Sets speed to 10 Mbps. Use the ifconfig mediaopt - option to select full-duplex mode. +An Intel(R) Ethernet Network Adapter using fiber-based connections, however, +will not attempt to auto-negotiate with its link partner since those adapters +operate only in full duplex and only at their native speed. - 100baseTX - Sets speed to 100 Mbps. Use the ifconfig mediaopt - option to select full-duplex mode. +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. - 1000baseTX - Sets speed to 1000 Mbps.

You cannot enable/disable one without the other. - To enable checksum offloading: +TSO +--- +TSO (TCP Segmentation Offload) supports both IPv4 and IPv6. TSO can be disabled +and enabled using the ifconfig utility or sysctl. - ifconfig rxcsum +NOTE: TSO requires Tx checksum, if Tx checksum is disabled, TSO will also be +disabled. - To disable checksum offloading: +NOTE: 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 or +82544-based adapters, as well as older adapters. - ifconfig -rxcsum +To enable/disable TSO in the stack: - To confirm the current setting: +# sysctl net.inet.tcp.tso=0 (or 1 to enable it) - ifconfig +Doing this disables/enables TSO in the stack and affects all installed adapters. - Look for the presence or absence of the following line: +To disable BOTH TSO IPv4 and IPv6: - options=3 +# ifconfig em -tso - See the ifconfig man page for further information. +To enable BOTH TSO IPv4 and IPv6: +# ifconfig em tso - TSO - --- - The FreeBSD driver offers support for TSO (TCP Segmentation Offload). +You can also enable/disable IPv4 TSO or IPv6 TSO individually. Simply replace +tso|-tso in the above command with tso4 or tso6. For example, to disable +TSO IPv4: - You can enable/disable it in two ways/places: +# ifconfig em -tso4 - - sysctl net.inet.tcp.tso=0 (or 1 to enable it) +To disable TSO IPv6: - Doing this disables TSO in the stack and will affect all adapters. +# ifconfig em -tso6 - - ifconfig emX -tso - Doing this will disable TSO only for this adapter. +MSI-X +----- +MSI or MSI-X can be turned off by an entry in /etc/sysctl.conf - To enable: + hw.em.enable_msi=0 - - ifconfig emX tso +Unload and reload the driver. - 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 Issues/Troubleshooting +============================ -Known Limitations -================= +Detected Tx Unit Hang in Quad Port Adapters +------------------------------------------- +In some cases ports 3 and 4 don't pass traffic and report 'Detected Tx Unit +Hang' followed by 'NETDEV WATCHDOG: emX: transmit timed out' errors. Ports 1 +and 2 do not show any errors and will pass traffic. - Detected Tx Unit Hang in Quad Port Adapters - ------------------------------------------- +This issue may be resolved by updating to the latest kernel and BIOS. You +should use an OS that fully supports Message Signaled Interrupts (MSI) and make +sure that MSI is enabled in your system's BIOS. - 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.
