It causes the driver to spawn up to -max_vfs worth of virtual function. - -Additional Configurations -========================= - - Jumbo Frames - ------------ - Jumbo Frames support is enabled by changing the MTU to a value larger than - the default of 1500. Use the ip command to increase the MTU size. - For example: - - ip link set dev eth<x> mtu 9000 - - This setting is not saved across reboots. - - Notes: - - - The maximum MTU setting for Jumbo Frames is 9216. This value coincides - with the maximum Jumbo Frames size of 9234 bytes. - - - Using Jumbo frames at 10 or 100 Mbps is not supported and may result in - poor performance or loss of link. - - ethtool - ------- - The driver utilizes the ethtool interface for driver configuration and - diagnostics, as well as displaying statistical information. The latest - version of ethtool can be found at: - - https://www.kernel.org/pub/software/network/ethtool/ - - Enabling Wake on LAN* (WoL) - --------------------------- - WoL is configured through the ethtool* utility. - - For instructions on enabling WoL with ethtool, refer to the ethtool man page. - - WoL will be enabled on the system during the next shut down or reboot. - For this driver version, in order to enable WoL, the igb driver must be - loaded when shutting down or rebooting the system. - - Wake On LAN is only supported on port A of multi-port adapters. - - Wake On LAN is not supported for the Intel(R) Gigabit VT Quad Port Server - Adapter. - - Multiqueue - ---------- - In this mode, a separate MSI-X vector is allocated for each queue and one - for "other" interrupts such as link status change and errors. All - interrupts are throttled via interrupt moderation. Interrupt moderation - must be used to avoid interrupt storms while the driver is processing one - interrupt. The moderation value should be at least as large as the expected - time for the driver to process an interrupt. Multiqueue is off by default. - - REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not - found, the system will fallback to MSI or to Legacy interrupts. - - MAC and VLAN anti-spoofing feature - ---------------------------------- - When a malicious driver attempts to send a spoofed packet, it is dropped by - the hardware and not transmitted. An interrupt is sent to the PF driver - notifying it of the spoof attempt. - - When a spoofed packet is detected the PF driver will send the following - message to the system log (displayed by the "dmesg" command): - - Spoof event(s) detected on VF(n) - - Where n=the VF that attempted to do the spoofing. - - Setting MAC Address, VLAN and Rate Limit Using IProute2 Tool - ------------------------------------------------------------ - You can set a MAC address of a Virtual Function (VF), a default VLAN and the - rate limit using the IProute2 tool. Download the latest version of the - iproute2 tool from Sourceforge if your version does not have all the - features you require. - - -Support -======= - -For general information, go to the Intel support website at: - - www.intel.com/support/ - -or the Intel Wired Networking project hosted by Sourceforge at: - - http://sourceforge.net/projects/e1000 - -If an issue is identified with the released source code on the supported -kernel with a supported adapter, email the specific information related -to the issue to e1000-devel@lists.sf.net |
