## Description

## Functions

### nm_device_ethernet_get_hw_address ()

    const char *
    nm_device_ethernet_get_hw_address (NMDeviceEthernet *device);

`nm_device_ethernet_get_hw_address` has been deprecated since version 1.24 and should not be used in newly-written code.

Use `nm_device_get_hw_address()` instead.

Gets the active hardware (MAC) address of the NMDeviceEthernet

[skip]

#### Parameters

device | a NMDeviceEthernet |

#### Returns

the active hardware address. This is the internal string used by the device, and must not be modified.

### nm_device_ethernet_get_permanent_hw_address ()

    const char *
    nm_device_ethernet_get_permanent_hw_address
                                   (NMDeviceEthernet *device);

Gets the permanent hardware (MAC) address of the NMDeviceEthernet

#### Parameters

device | a NMDeviceEthernet |

#### Returns

the permanent hardware address. This is the internal string used by the device, and must not be modified.

### nm_device_ethernet_get_speed ()

    guint32
    nm_device_ethernet_get_speed (NMDeviceEthernet *device);

Gets the speed of the NMDeviceEthernet in Mbit/s.

#### Parameters

device | a NMDeviceEthernet |

#### Returns

the speed of the device in Mbit/s

### nm_device_ethernet_get_carrier ()

    gboolean
    nm_device_ethernet_get_carrier (NMDeviceEthernet *device);

Whether the device has carrier.

#### Parameters

device | a NMDeviceEthernet |

#### Returns

`TRUE` if the device has carrier

### nm_device_ethernet_get_s390_subchannels ()

    const char *const *
    nm_device_ethernet_get_s390_subchannels
                                   (NMDeviceEthernet *device);

Return the list of s390 subchannels if the device supports them.

#### Parameters

device | a NMDeviceEthernet |

#### Returns

array of strings, each specifying one subchannel the s390 device uses to communicate to the host.
