# [DESCRIPTION](#DESCRIPTION)

## [vdpa dev show - display vdpa device attributes](#vdpa_dev_show_-_display_vdpa_device_attributes)

*DEV* - specifies the vdpa device to show. If this argument is omitted all devices are listed.

Format is:  
VDPA\_DEVICE\_NAME

## [vdpa dev add - add a new vdpa device.](#vdpa_dev_add_-_add_a_new_vdpa_device.)

[**name NAME**](#name)

Name of the new vdpa device to add.

[**mgmtdev MGMTDEV**](#mgmtdev)

Name of the management device to use for device addition.

**device\_features DEVICE\_FEATURES** Specifies the virtio device features bit-mask that is provisioned for the new vdpa device.

The bits can be found under include/uapi/linux/virtio\*.h.

See macros such as VIRTIO\_F_ and VIRTIO\_XXX (e.g., NET)\_F_ for specific bit values.

This is optional.

**mac MACADDR** - specifies the mac address for the new vdpa device. This is applicable only for the network type of vdpa device. This is optional.

**mtu MTU** - specifies the mtu for the new vdpa device. This is applicable only for the network type of vdpa device. This is optional.

## [vdpa dev del - Delete the vdpa device.](#vdpa_dev_del_-_Delete_the_vdpa_device.)

*DEV* - specifies the vdpa device to delete.

## [vdpa dev config show - Show configuration of specific device or all devices.](#vdpa_dev_config_show_-_Show_configuration_of_specific_device_or_all_devices.)

*DEV* - specifies the vdpa device to show its configuration. If this argument is omitted all devices configuration is listed.

Format is:  
VDPA\_DEVICE\_NAME

## [vdpa dev vstats show - show vendor specific statistics](#vdpa_dev_vstats_show_-_show_vendor_specific_statistics)

Shows vendor specific statistics for the given device and virtqueue index. The information is presented as name-value pairs where name is the name of the field and value is a numeric value for it.
