When %TRUE, enforce auto-negotiation of speed and duplex mode. If "speed" and "duplex" properties are both specified, only that single mode will be advertised and accepted during the link auto-negotiation process: this works only for BASE-T 802.3 specifications and is useful for enforcing gigabits modes, as in these cases link negotiation is mandatory. When %FALSE, "speed" and "duplex" properties should be both set or link configuration will be skipped.
If specified, request that the device use this MAC address instead. This is known as MAC cloning or spoofing.
Beside explicitly specifying a MAC address, the special values "preserve", "permanent", "random" and "stable" are supported. "preserve" means not to touch the MAC address on activation. "permanent" means to use the permanent hardware address if the device has one (otherwise this is treated as "preserve"). "random" creates a random MAC address on each connect. "stable" creates a hashed MAC address based on connection.stable-id and a machine dependent key.
If unspecified, the value can be overwritten via global defaults, see manual of NetworkManager.conf. If still unspecified, it defaults to "preserve" (older versions of NetworkManager may use a different default value).
On D-Bus, this field is expressed as "assigned-mac-address" or the deprecated "cloned-mac-address".
When a value is set, either "half" or "full", configures the device to use the specified duplex mode. If "auto-negotiate" is "yes" the specified duplex mode will be the only one advertised during link negotiation: this works only for BASE-T 802.3 specifications and is useful for enforcing gigabits modes, as in these cases link negotiation is mandatory. If the value is unset (the default), the link configuration will be either skipped (if "auto-negotiate" is "no", the default) or will be auto-negotiated (if "auto-negotiate" is "yes") and the local device will advertise all the supported duplex modes. Must be set together with the "speed" property if specified. Before specifying a duplex mode be sure your device supports it.
With #NMSettingWired:cloned-mac-address setting "random" or "stable", by default all bits of the MAC address are scrambled and a locally-administered, unicast MAC address is created. This property allows to specify that certain bits are fixed. Note that the least significant bit of the first MAC address will always be unset to create a unicast MAC address.
If the property is %NULL, it is eligible to be overwritten by a default connection setting. If the value is still %NULL or an empty string, the default is to create a locally-administered, unicast MAC address.
If the value contains one MAC address, this address is used as mask. The set bits of the mask are to be filled with the current MAC address of the device, while the unset bits are subject to randomization. Setting "FE:FF:FF:00:00:00" means to preserve the OUI of the current MAC address and only randomize the lower 3 bytes using the "random" or "stable" algorithm.
If the value contains one additional MAC address after the mask, this address is used instead of the current MAC address to fill the bits that shall not be randomized. For example, a value of "FE:FF:FF:00:00:00 68:F7:28:00:00:00" will set the OUI of the MAC address to 68:F7:28, while the lower bits are randomized. A value of "02:00:00:00:00:00 00:00:00:00:00:00" will create a fully scrambled globally-administered, burned-in MAC address.
If the value contains more than one additional MAC addresses, one of them is chosen randomly. For example, "02:00:00:00:00:00 00:00:00:00:00:00 02:00:00:00:00:00" will create a fully scrambled MAC address, randomly locally or globally administered.
If specified, this connection will only apply to the Ethernet device whose permanent MAC address matches. This property does not change the MAC address of the device (i.e. MAC spoofing).
If specified, this connection will never apply to the Ethernet device whose permanent MAC address matches an address in the list. Each MAC address is in the standard hex-digits-and-colons notation (00:11:22:33:44:55).
If non-zero, only transmit packets of the specified size or smaller, breaking larger packets up into multiple Ethernet frames.
Specific port type to use if the device supports multiple attachment methods. One of "tp" (Twisted Pair), "aui" (Attachment Unit Interface), "bnc" (Thin Ethernet) or "mii" (Media Independent Interface). If the device supports only one port type, this setting is ignored.
s390 network device type; one of "qeth", "lcs", or "ctc", representing the different types of virtual network devices available on s390 systems.
Dictionary of key/value pairs of s390-specific device options. Both keys and values must be strings. Allowed keys include "portno", "layer2", "portname", "protocol", among others. Key names must contain only alphanumeric characters (ie, [a-zA-Z0-9]).
Currently, NetworkManager itself does nothing with this information. However, s390utils ships a udev rule which parses this information and applies it to the interface.
Identifies specific subchannels that this network device uses for communication with z/VM or s390 host. Like the #NMSettingWired:mac-address property for non-z/VM devices, this property can be used to ensure this connection only applies to the network device that uses these subchannels. The list should contain exactly 3 strings, and each string may only be composed of hexadecimal characters and the period (.) character.
When a value greater than 0 is set, configures the device to use the specified speed. If "auto-negotiate" is "yes" the specified speed will be the only one advertised during link negotiation: this works only for BASE-T 802.3 specifications and is useful for enforcing gigabit speeds, as in this case link negotiation is mandatory. If the value is unset (0, the default), the link configuration will be either skipped (if "auto-negotiate" is "no", the default) or will be auto-negotiated (if "auto-negotiate" is "yes") and the local device will advertise all the supported speeds. In Mbit/s, ie 100 == 100Mbit/s. Must be set together with the "duplex" property when non-zero. Before specifying a speed value be sure your device supports it.
The #NMSettingWiredWakeOnLan options to enable. Not all devices support all options. May be any combination of %NM_SETTING_WIRED_WAKE_ON_LAN_PHY, %NM_SETTING_WIRED_WAKE_ON_LAN_UNICAST, %NM_SETTING_WIRED_WAKE_ON_LAN_MULTICAST, %NM_SETTING_WIRED_WAKE_ON_LAN_BROADCAST, %NM_SETTING_WIRED_WAKE_ON_LAN_ARP, %NM_SETTING_WIRED_WAKE_ON_LAN_MAGIC or the special values %NM_SETTING_WIRED_WAKE_ON_LAN_DEFAULT (to use global settings) and %NM_SETTING_WIRED_WAKE_ON_LAN_IGNORE (to disable management of Wake-on-LAN in NetworkManager).
If specified, the password used with magic-packet-based Wake-on-LAN, represented as an Ethernet MAC address. If %NULL, no password will be required.
When %TRUE, setup the interface to accept packets for all MAC addresses. This is enabling the kernel interface flag IFF_PROMISC. When %FALSE, the interface will only accept the packets with the interface destination mac address or broadcast.
