igb(4) Kernel Interfaces Manual igb(4) FreeBSD Ports 14.quarterly June 10, 2019 igb(4) ------------------------------------------------------------------------------- IGB(4) Kernel Interfaces Manual IGB(4) NAME igb -- Intel(R) Ethernet Driver for the FreeBSD* operating system SYNOPSIS device igb DESCRIPTION The igb driver provides support for Intel(R) Ethernet devices based on the Intel 82575 Ethernet controller chips. For questions related to hardware requirements, refer to the documenta- tion supplied with your adapter. Support for Jumbo Frames is provided via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility configures the adapter to receive and transmit Jumbo Frames. The maxi- mum MTU setting for Jumbo Frames is 9216. This value coincides with the maximum Jumbo Frames size of 9238. This driver version supports VLANs. For information on enabling VLANs, see the README. The igb driver sup- ports the following media types: autoselect Enables auto-negotiation for speed and duplex. 10baseT/UTP Sets 10Mbps operation. Use the mediaopt option to select full-duplex mode. 100baseTX Sets 100Mbps operation. Use the mediaopt option to select full-duplex mode. 1000baseSX Sets 1000Mbps operation. Only full-duplex mode is sup- ported at this speed. 1000baseTX Sets 1000Mbps operation. Only full-duplex mode is sup- ported at this speed. The igb driver supports both full-duplex and half-duplex. Use mediaopt to force the driver to either of these settings. Note that the only valid parameter for mediaopt is full-duplex; to force the driver to half-duplex when running at less than gibabit speed, leave mediaopt un- specified. For more information on configuring this device, see ifconfig(8). DIAGNOSTICS igb%d: Unable to allocate bus resource: memory A fatal initialization error has occurred. igb%d: Unable to allocate bus resource: interrupt A fatal initializa- tion error has occurred. igb%d: watchdog timeout -- resetting The device has stopped responding to the network, or there is a problem with the network connection (ca- ble). SUPPORT For additional information regarding building and installation, see the README included with the driver. For general information, go to the Intel support website at: http://www.intel.com/support/ If an issue is identified with the released source code on a supported kernel with a supported adapter, email the specific information related to the issue to freebsd@intel.com SEE ALSO arp(4), netintro(4), ng_ether(4), vlan(4), ifconfig(8) HISTORY The igb device driver first appeared in FreeBSD 4.4.
