1	Linux* Base Driver for Intel(R) Network Connection
2	==================================================
3	
4	Intel Gigabit Linux driver.
5	Copyright(c) 1999 - 2010 Intel Corporation.

14	Identifying Your Adapter
15	========================
16	
17	This driver supports all 82575, 82576 and 82580-based Intel (R) gigabit network
18	connections.
19	
20	For specific information on how to identify your adapter, go to the Adapter &
21	Driver ID Guide at:
22	
23	    http://support.intel.com/support/go/network/adapter/idguide.htm
24	
25	Command Line Parameters
26	=======================
27	
28	The default value for each parameter is generally the recommended setting,
29	unless otherwise noted.
30	
31	max_vfs
32	-------
33	Valid Range:   0-7
34	Default Value: 0
35	
36	This parameter adds support for SR-IOV.  It causes the driver to spawn up to
37	max_vfs worth of virtual function.
38	
39	
40	Additional Configurations
41	=========================
42	
43	  Jumbo Frames
44	  ------------
45	  Jumbo Frames support is enabled by changing the MTU to a value larger than
46	  the default of 1500.  Use the ifconfig command to increase the MTU size.
47	  For example:
48	
49	       ifconfig eth<x> mtu 9000 up
50	
51	  This setting is not saved across reboots.
52	
53	  Notes:
54	
55	  - The maximum MTU setting for Jumbo Frames is 9216.  This value coincides
56	    with the maximum Jumbo Frames size of 9234 bytes.
57	
58	  - Using Jumbo Frames at 10 or 100 Mbps may result in poor performance or
59	    loss of link.
60	
61	  Ethtool
62	  -------
63	  The driver utilizes the ethtool interface for driver configuration and
64	  diagnostics, as well as displaying statistical information. The latest
65	  version of ethtool can be found at:
66	
67	  http://ftp.kernel.org/pub/software/network/ethtool/
68	
69	  Enabling Wake on LAN* (WoL)
70	  ---------------------------
71	  WoL is configured through the ethtool* utility.
72	
73	  For instructions on enabling WoL with ethtool, refer to the ethtool man page.
74	
75	  WoL will be enabled on the system during the next shut down or reboot.
76	  For this driver version, in order to enable WoL, the igb driver must be
77	  loaded when shutting down or rebooting the system.
78	
79	  Wake On LAN is only supported on port A of multi-port adapters.
80	
81	  Wake On LAN is not supported for the Intel(R) Gigabit VT Quad Port Server
82	  Adapter.
83	
84	  Multiqueue
85	  ----------
86	  In this mode, a separate MSI-X vector is allocated for each queue and one
87	  for "other" interrupts such as link status change and errors.  All
88	  interrupts are throttled via interrupt moderation.  Interrupt moderation
89	  must be used to avoid interrupt storms while the driver is processing one
90	  interrupt.  The moderation value should be at least as large as the expected
91	  time for the driver to process an interrupt. Multiqueue is off by default.
92	
93	  REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not
94	  found, the system will fallback to MSI or to Legacy interrupts.
95	
96	  MAC and VLAN anti-spoofing feature
97	  ----------------------------------
98	  When a malicious driver attempts to send a spoofed packet, it is dropped by
99	  the hardware and not transmitted.  An interrupt is sent to the PF driver
100	  notifying it of the spoof attempt.
101	
102	  When a spoofed packet is detected the PF driver will send the following
103	  message to the system log (displayed by  the "dmesg" command):
104	
105	  Spoof event(s) detected on VF(n)
106	
107	  Where n=the VF that attempted to do the spoofing.
108	
109	Support
110	=======
111	
112	For general information, go to the Intel support website at:
113	
114	    www.intel.com/support/
115	
116	or the Intel Wired Networking project hosted by Sourceforge at:
117	
118	    http://sourceforge.net/projects/e1000
119	
120	If an issue is identified with the released source code on the supported
121	kernel with a supported adapter, email the specific information related
122	to the issue to e1000-devel@lists.sf.net
