# NAME

`ixg` —
Intel(R) 10Gb Ethernet driver

# SYNOPSIS

`ixg* at pci? dev ? function ?`

# DESCRIPTION

The `ixg` driver provides support for PCI 10Gb Ethernet adapters based on the Intel(R) 82598EB, 82599, X540 and X550 Ethernet Controllers. The driver supports Jumbo Frames, TCP Segmentation Offload (TSO).

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

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. On NetBSD, the maximum MTU size for Jumbo Frames is 9000 bytes.

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

# DIAGNOSTICS

  A fatal initialization error has occurred.
ixg%d: Unable to allocate bus resource: interrupt
  A fatal initialization error has occurred.
ixg%d: watchdog timeout -- resetting
  The device has stopped responding to the network, or there is a problem with the network connection (cable).

# HISTORY

The `ixg` device driver comes from FreeBSD, where it is called `ixgbe`. It first appeared in NetBSD 6.0.

# AUTHORS

The `ixg` driver was written by Intel Corporation <freebsdnic@mailbox.intel.com>. It was imported from FreeBSD into NetBSD by
David Young <dyoung@NetBSD.org>.

# BUGS

The hardware supports a maximum MTU of 16114 bytes, but the NetBSD port of the driver supports only 9000 bytes.
