Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
The ixgb driver provides support for PCI Gigabit Ethernet adapters based
on the Intel 82597EX Ethernet controller chips. The driver supports
Transmit/Receive checksum offload and Jumbo Frames.
For questions related to hardware requirements, refer to the documenta‐
tion supplied with your Intel PRO/10GbE adapter. All hardware require‐
ments listed apply to use with FreeBSD.
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 ixgb driver supports the following cards:
· Intel PRO/10GbE LR Server Adapter
· Intel PRO/10GbE SR Server Adapter
