41 To compile this driver into the kernel,
42 place the following lines in your
43 kernel configuration file:
44 .Bd -ragged -offset indent
49 To load the driver as a
50 module at boot time, place the following line in
52 .Bd -literal -offset indent
58 driver supports Transmit/Receive checksum offload,
59 Jumbo Frames as well as TCP segmentation offload (TSO).
60 For further hardware information, see
61 .Pa http://www.chelsio.com/ .
63 For questions related to hardware requirements,
64 refer to the documentation supplied with your Chelsio T3 adapter.
65 All hardware requirements listed apply to use with
68 Support for Jumbo Frames is provided via the interface MTU setting.
69 Selecting an MTU larger than 1500 bytes with the
71 utility configures the adapter to receive and transmit Jumbo Frames.
72 The maximum MTU size for Jumbo Frames is 9000.
74 For more information on configuring this device, see
79 driver supports 10 Gigabit Ethernet adapters based on the T3 and T3B chipset:
90 Tunables can be set at the
92 prompt before booting the kernel or stored in
94 .Bl -tag -width indent
