## Properties

Table 81.

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---
    mac-address
    byte array
| If specified, this connection will only apply to the IPoIB device whose permanent MAC address matches. This property does not change the MAC address of the device (i.e. MAC spoofing).
    mtu
    uint32
    0
| If non-zero, only transmit packets of the specified size or smaller, breaking larger packets up into multiple frames.
    p-key
    int32
    -1
| The InfiniBand P_Key to use for this device. A value of -1 means to use the default P_Key (aka "the P_Key at index 0"). Otherwise it is a 16-bit unsigned integer, whose high bit is set if it is a "full membership" P_Key.
    parent
    string
| The interface name of the parent device of this device. Normally NULL, but if the "p_key" property is set, then you must specify the base device by setting either this property or "mac-address".
    transport-mode
    string
| The IP-over-InfiniBand transport mode. Either "datagram" or "connected".
