SPDX-License-Identifier: GPL-2.0+ - -============================================================= -Linux Base Driver for Intel(R) Ethernet Multi-host Controller -============================================================= - -August 20, 2018 -Copyright(c) 2015-2018 Intel Corporation. - -Contents -======== -- Identifying Your Adapter -- Additional Configurations -- Performance Tuning -- Known Issues -- Support - -Identifying Your Adapter -======================== -The driver in this release is compatible with devices based on the Intel(R) -Ethernet Multi-host Controller. - -For information on how to identify your adapter, and for the latest Intel -network drivers, refer to the Intel Support website: -http://www.intel.com/support - - -Flow Control ------------- -The Intel(R) Ethernet Switch Host Interface Driver does not support Flow -Control. It will not send pause frames. This may result in dropped frames. - - -Virtual Functions (VFs) ------------------------ -Use sysfs to enable VFs. -Valid Range: 0-64 - -For example:: - - echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs //enable VFs - echo 0 > /sys/class/net/$dev/device/sriov_numvfs //disable VFs - -NOTE: Neither the device nor the driver control how VFs are mapped into config -space. Bus layout will vary by operating system. On operating systems that -support it, you can check sysfs to find the mapping. - -NOTE: When SR-IOV mode is enabled, hardware VLAN filtering and VLAN tag -stripping/insertion will remain enabled. Please remove the old VLAN filter -before the new VLAN filter is added. For example:: - - ip link set eth0 vf 0 vlan 100 // set vlan 100 for VF 0 - ip link set eth0 vf 0 vlan 0 // Delete vlan 100 - ip link set eth0 vf 0 vlan 200 // set a new vlan 200 for VF 0 - - -Additional Features and Configurations -====================================== - -Jumbo Frames ------------- -Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU) -to a value larger than the default value of 1500. - -Use the ifconfig command to increase the MTU size. For example, enter the -following where <x> is the interface number:: - - ifconfig eth<x> mtu 9000 up - -Alternatively, you can use the ip command as follows:: - - ip link set mtu 9000 dev eth<x> - ip link set up dev eth<x> - -This setting is not saved across reboots. The setting change can be made -permanent by adding 'MTU=9000' to the file: - -- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x> -- For SLES: /etc/sysconfig/network/<config_file> - -NOTE: The maximum MTU setting for Jumbo Frames is 15342. This value coincides -with the maximum Jumbo Frames size of 15364 bytes. - -NOTE: This driver will attempt to use multiple page sized buffers to receive -each jumbo packet. This should help to avoid buffer starvation issues when -allocating receive packets. - - -Generic Receive Offload, aka GRO --------------------------------- -The driver supports the in-kernel software implementation of GRO. GRO has -shown that by coalescing Rx traffic into larger chunks of data, CPU -utilization can be significantly reduced when under large Rx load. GRO is an -evolution of the previously-used LRO interface. GRO is able to coalesce -other protocols besides TCP. It's also safe to use with configurations that -are problematic for LRO, namely bridging and iSCSI. - - - -Supported ethtool Commands and Options for Filtering ----------------------------------------------------- --n --show-nfc - Retrieves the receive network flow classification configurations. - -rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 - Retrieves the hash options for the specified network traffic type. - --N --config-nfc - Configures the receive network flow classification. - -rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 m|v|t|s|d|f|n|r - Configures the hash options for the specified network traffic type. - -- udp4: UDP over IPv4 -- udp6: UDP over IPv6 -- f Hash on bytes 0 and 1 of the Layer 4 header of the rx packet. -- n Hash on bytes 2 and 3 of the Layer 4 header of the rx packet. - - -Known Issues/Troubleshooting -============================ - -Enabling SR-IOV in a 64-bit Microsoft Windows Server 2012/R2 guest OS under Linux KVM -------------------------------------------------------------------------------------- -KVM Hypervisor/VMM supports direct assignment of a PCIe device to a VM. This -includes traditional PCIe devices, as well as SR-IOV-capable devices based on -the Intel Ethernet Controller XL710. - - -Support -======= -For general information, go to the Intel support website at: - -https://www.intel.com/support/ - -or the Intel Wired Networking project hosted by Sourceforge at: - -https://sourceforge.net/projects/e1000 - -If an issue is identified with the released source code on a supported kernel -with a supported adapter, email the specific information related to the issue -to e1000-devel@lists.sf.net. |
