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 (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,
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 NetBSD 6.0.
The ixg driver was written by Intel Corporation
<freebsdnicATmailbox.com>. It was imported from FreeBSD into NetBSD
David Young <dyoungATNetBSD.org>.
The hardware supports a maximum MTU of 16114 bytes, but the NetBSD port
of the driver supports 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.
