Format is an hexadecimal + value. This is used to disambiguate interfaces which might be + stacked (e.g: VLAN interfaces) but still have the same MAC + address as their parent device. + +What: /sys/class/net/<iface>/dormant +Date: March 2006 +KernelVersion: 2.6.17 +Contact: netdev@vger.kernel.org +Description: + Indicates whether the interface is in dormant state. Possible + values are: + 0: interface is not dormant + 1: interface is dormant + + This attribute can be used by supplicant software to signal that + the device is not usable unless some supplicant-based + authentication is performed (e.g: 802.1x).

This attribute is used for mapping an interface + identifier to an interface name. It is used throughout the + networking stack for specifying the interface specific + requests/events. + +What: /sys/class/net/<iface>/iflink +Date: April 2005 +KernelVersion: 2.6.12 +Contact: netdev@vger.kernel.org +Description: + Indicates the system-wide interface unique index identifier a + the interface is linked to. Format is decimal. This attribute is + used to resolve interfaces chaining, linking and stacking. + Physical interfaces have the same 'ifindex' and 'iflink' values. + +What: /sys/class/net/<iface>/link_mode +Date: March 2006 +KernelVersion: 2.6.17 +Contact: netdev@vger.kernel.org +Description: + Indicates the interface link mode, as a decimal number. This + attribute should be used in conjunction with 'dormant' attribute + to determine the interface usability.

Specific values depends on the + lower-level interface protocol used. Ethernet devices will show + a 'mtu' attribute value of 1500 unless changed. + +What: /sys/calss/net/<iface>/netdev_group +Date: January 2011 +KernelVersion: 2.6.39 +Contact: netdev@vger.kernel.org +Description: + Indicates the interface network device group, as a decimal + integer. Default value is 0 which corresponds to the initial + network devices group. The group can be changed to affect + routing decisions (see: net/ipv4/fib_rules and + net/ipv6/fib6_rules.c). + +What: /sys/class/net/<iface>/operstate +Date: March 2006 +KernelVersion: 2.6.17 +Contact: netdev@vger.kernel.org +Description: + Indicates the interface RFC2863 operational state as a string. + Possible values are: + "unknown", "notpresent", "down", "lowerlayerdown", "testing", + "dormant", "up". + +What: /sys/class/net/<iface>/speed +Date: October 2009 +KernelVersion: 2.6.33 +Contact: netdev@vger.kernel.org +Description: + Indicates the interface latest or current speed value.
