4 i40e - Intel 710/722 Ethernet Device Driver

6 SYNOPSIS
7 /dev/net/i40e*
8
9 DESCRIPTION
10 The i40e driver is a GLDv3, multi-threaded, clonable, loadable device
11 driver that supports the Data Link Provider Interface, dlpi(7P). The
12 i40e driver supports the Intel 710 and 722 Ethernet Controller families
13 of networking interface cards which come in 1 GbE, 10 GbE, 25 GbE, and 40
14 GbE variants.
15
16 In addition to basic device initialization and the sending and receiving
17 of frames, it supports the following features:
18
19 - Jumbo frames up to 9710 bytes.
20
21 - Promiscuous access via snoop(1M) and dlpi(7P)
22
23 - IPv4 Checksum Offload
24
25 - TCP, UDP, and SCTP checksum offload
26
27 - IPv4 and IPv6 TCP Segmentation offload
28
29 At this time, the i40e driver does not enable the use of energy efficient
30 Ethernet (EEE) or support the use of flow control through hardware pause
31 frames.
32
33 APPLICATION PROGRAMMING INTERFACE
34 For each device supported by the i40e installed in the system, a
170 The tx_lso_enable property controls whether or not the device
171 enables support for Large Segment Offloand (LSO) when
172 transmitting packets. The default is to always enable support
173 for this. Turning it off will decrease throughput when
174 transmitting packets, but should be done if a hardware bug is
175 suspected.

177 ARCHITECTURE
178 The i40e driver is only supported on x86 systems at this time.
