     ixgbe — Intel(R) 10Gb Ethernet driver for the FreeBSD operating system


     To compile this driver into the kernel, place the following lines in your kernel
     configuration file:

           device iflib
           device ixgbe

     Alternatively, to load the driver as a module at boot time, place the following line in



     The ixgbe driver provides support for PCI 10Gb Ethernet adapters based on the Intel 82598EB
     Intel(R) Network Connections.  The driver supports Jumbo Frames, MSIX, TSO, and RSS.

     For questions related to hardware requirements, refer to the documentation supplied with
     your Intel 10GbE adapter.  All hardware requirements listed apply to use with FreeBSD.

     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 maximum MTU size for Jumbo Frames is 16114.

     This driver version supports VLANs.  For information on enabling VLANs, see ifconfig(8).


     The ixgbe driver supports the following cards:

        Intel(R) 10 Gigabit XF SR/AF Dual Port Server Adapter
        Intel(R) 10 Gigabit XF SR/LR Server Adapter
        Intel(R) 82598EB 10 Gigabit AF Network Connection
        Intel(R) 82598EB 10 Gigabit AT CX4 Network Connection

     If an issue is identified with the released source code on the supported kernel with a
     supported adapter, email the specific information related to the issue to


     altq(4), arp(4), netintro(4), ng_ether(4), polling(4), vlan(4), ifconfig(8)


     The ixgbe device driver first appeared in FreeBSD 7.0.
