NAME

ix -- Intel(R) 10Gb Ethernet driver

SYNOPSIS

To compile this driver into the kernel, place the following line in your kernel configuration file: device ix Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_ix_load="YES"

DESCRIPTION

The ix driver provides support for PCI 10Gb Ethernet adapters based on the Intel 82598EB, 82599 and X540 Intel(R) Network Connections. The driver supports Jumbo Frames, MSIX, TSO, and RSS. For questions related to hardware requirements, refer to the documenta- tion supplied with your Intel 10GbE adapter. All hardware requirements listed apply to use with DragonFly. 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).
