NAME
     ixgb — Intel(R) PRO/10GbE Ethernet driver for the FreeBSD operating sys‐
     tem

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

	   device ixgb

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

	   if_ixgb_load="YES"

DESCRIPTION
     The ixgb driver provides support for PCI Gigabit Ethernet adapters based
     on the Intel 82597EX Ethernet controller chips.  The driver supports
     Transmit/Receive checksum offload and Jumbo Frames.

     For questions related to hardware requirements, refer to the documenta‐
     tion supplied with your Intel PRO/10GbE adapter.  All hardware require‐
     ments 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 con‐
     figures 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).

HARDWARE
     The ixgb driver supports the following cards:

     ·	 Intel PRO/10GbE LR Server Adapter
     ·	 Intel PRO/10GbE SR Server Adapter
