ixgbe -- Intel(R) 10Gb Ethernet driver for the DragonFly BSD operating
To compile this driver into the kernel, place the following line in your
kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
The ixgbe driver provides support for PCI 10Gb Ethernet adapters based on
the Intel 82598EB 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,
The ixgbe driver supports the following cards:
* Intel(R) 10 Gigabit XF SR/AF Dual Port Server Adapter
* Intel(R) 10 Gigabit XF SR/LR Server Adapter
* Intel(R) 82598EB 10 Gigabit AF Network Connection
* Intel(R) 82598EB 10 Gigabit AT CX4 Network Connection
The default DragonFly configuration may not give the best possible per-
formance with single streams TCP connections. Increasing the value of
the net.inet.tcp.sosend_agglim sysctl to 12 or more will increase sending
