| | 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 ip command to increase the MTU size. |
| | 46 | For example: |
| | 47 | |
| | 48 | ip link set dev eth<x> mtu 9000 |
| | 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. |
