39 To compile this driver into the kernel,
40 place the following lines in your
41 kernel configuration file:
42 .Bd -ragged -offset indent
47 To load the driver as a
48 module at boot time, place the following line in
50 .Bd -literal -offset indent
56 driver supports Transmit/Receive checksum offload,
57 Jumbo Frames, TCP segmentation offload (TSO), Large Receive Offload (LRO),
58 VLAN hardware insertion / extraction, and VLAN checksum offload.
59 For further hardware information, see
60 .Pa http://www.chelsio.com/ .
62 For questions related to hardware requirements,
63 refer to the documentation supplied with your Chelsio T3 adapter.
64 All hardware requirements listed apply to use with
67 Support for Jumbo Frames is provided via the interface MTU setting.
68 Selecting an MTU larger than 1500 bytes with the
70 utility configures the adapter to receive and transmit Jumbo Frames.
71 The maximum MTU size for Jumbo Frames is 9000.
73 For more information on configuring this device, see
78 driver supports 10 Gigabit and 1 Gigabit Ethernet adapters based on the T3 and T3B chipset:
