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".
