ixg -- Intel(R) 10Gb Ethernet driver
ixg* at pci? dev ? function ?
The ixg driver provides support for PCI 10Gb Ethernet adapters based on the Intel(R) 82598EB
and 82599 10 GbE Controllers. The driver supports Jumbo Frames, TCP Segmentation Offload
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).
The ixg driver supports the following cards:
o Intel(R) 10 Gigabit XF SR/AF Dual Port Server Adapter
o Intel(R) 10 Gigabit XF SR/LR Server Adapter
o Intel(R) 82598EB 10 Gigabit AF Network Connection
o Intel(R) 82598EB 10 Gigabit AT CX4 Network Connection

The ixg device driver comes from FreeBSD, where it is called ixgbe(4). It first appeared in
The ixg driver was written by Intel Corporation <firstname.lastname@example.org>. It was
imported from FreeBSD into NetBSD by
David Young <dyoung@NetBSD.org>.
The hardware supports a maximum MTU of 16114 bytes, but the NetBSD port of the driver sup-
ports only 9000 bytes.
The hardware supports Message-Signalled Interrupts (MSI and MSI-X) and Receive-Side Scaling
(RSS), however, these features are not enabled in the NetBSD driver at this time.
