1	Linux* Base Driver for Intel(R) Ethernet Network Connection
2	===========================================================
3	
4	Intel Gigabit Linux driver.
5	Copyright(c) 1999 - 2013 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	Additional Configurations
40	=========================
41	
42	  Jumbo Frames
43	  ------------
44	  Jumbo Frames support is enabled by changing the MTU to a value larger than
45	  the default of 1500.  Use the ifconfig command to increase the MTU size.
46	  For example:
47	
48	       ifconfig eth<x> mtu 9000 up
49	
50	  This setting is not saved across reboots.
51	
52	  Notes:
53	
54	  - The maximum MTU setting for Jumbo Frames is 9216.  This value coincides
55	    with the maximum Jumbo Frames size of 9234 bytes.
56	
57	  - Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
58	    poor performance or loss of link.
59	
60	  ethtool
61	  -------
62	  The driver utilizes the ethtool interface for driver configuration and
63	  diagnostics, as well as displaying statistical information. The latest
64	  version of ethtool can be found at:
65	
66	  http://ftp.kernel.org/pub/software/network/ethtool/
67	
68	  Enabling Wake on LAN* (WoL)
69	  ---------------------------
70	  WoL is configured through the ethtool* utility.
71	
72	  For instructions on enabling WoL with ethtool, refer to the ethtool man page.
73	
74	  WoL will be enabled on the system during the next shut down or reboot.
75	  For this driver version, in order to enable WoL, the igb driver must be
76	  loaded when shutting down or rebooting the system.
77	
78	  Wake On LAN is only supported on port A of multi-port adapters.
79	
80	  Wake On LAN is not supported for the Intel(R) Gigabit VT Quad Port Server
81	  Adapter.
82	
83	  Multiqueue
84	  ----------
85	  In this mode, a separate MSI-X vector is allocated for each queue and one
86	  for "other" interrupts such as link status change and errors.  All
87	  interrupts are throttled via interrupt moderation.  Interrupt moderation
88	  must be used to avoid interrupt storms while the driver is processing one
89	  interrupt.  The moderation value should be at least as large as the expected
90	  time for the driver to process an interrupt. Multiqueue is off by default.
91	
92	  REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not
93	  found, the system will fallback to MSI or to Legacy interrupts.
94	
95	  MAC and VLAN anti-spoofing feature
96	  ----------------------------------
97	  When a malicious driver attempts to send a spoofed packet, it is dropped by
98	  the hardware and not transmitted.  An interrupt is sent to the PF driver
99	  notifying it of the spoof attempt.
100	
101	  When a spoofed packet is detected the PF driver will send the following
102	  message to the system log (displayed by  the "dmesg" command):
103	
104	  Spoof event(s) detected on VF(n)
105	
106	  Where n=the VF that attempted to do the spoofing.
107	
108	  Setting MAC Address, VLAN and Rate Limit Using IProute2 Tool
109	  ------------------------------------------------------------
110	  You can set a MAC address of a Virtual Function (VF), a default VLAN and the
111	  rate limit using the IProute2 tool. Download the latest version of the
112	  iproute2 tool from Sourceforge if your version does not have all the
113	  features you require.
114	
115	
116	Support
117	=======
118	
119	For general information, go to the Intel support website at:
120	
121	    www.intel.com/support/
122	
123	or the Intel Wired Networking project hosted by Sourceforge at:
124	
125	    http://sourceforge.net/projects/e1000
126	
127	If an issue is identified with the released source code on the supported
128	kernel with a supported adapter, email the specific information related
129	to the issue to e1000-devel@lists.sf.net
