NAME
cxgb
- Chelsio T3 10 Gigabit Ethernet adapter driver
SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
device firmwaredevice cxgb
To load the driver as a
module at boot time, place the following line in
loader.conf5:
if_cxgb_load="YES"
DESCRIPTION
The
driver supports Transmit/Receive checksum offload,
Jumbo Frames, TCP segmentation offload (TSO), Large Receive Offload (LRO),
VLAN hardware insertion / extraction, and VLAN checksum offload.
For further hardware information, see
http://www.chelsio.com/
For questions related to hardware requirements,
refer to the documentation supplied with your Chelsio T3 adapter.
All hardware requirements listed apply to use with
Fx .
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.
The maximum MTU size for Jumbo Frames is 9000.
For more information on configuring this device, see
ifconfig(8).
HARDWARE
The
driver supports 10 Gigabit and 1 Gigabit Ethernet adapters based on the T3 and T3B chipset:
Chelsio 10GBase-CX4
Chelsio 10GBase-LR
Chelsio 10GBase-SR
LOADER TUNABLES
Tunables can be set at the
loader(8)
prompt before booting the kernel or stored in
loader.conf5.
