VOID Ip6CleanInterface | ( | IN IP6_INTERFACE * | Interface, | |

Free the interface used by IpInstance. All the IP instance with the same Ip/prefix pair share the same interface. It is reference counted. All the frames that haven't been sent will be cancelled. Because the IpInstance is optional, the caller must remove IpInstance from the interface's instance list.
[in] | Interface | The interface used by the IpInstance. |
[in] | IpInstance | The IP instance that free the interface. NULL if the IP driver is releasing the default interface. |

Create an IP6_INTERFACE.

[in] | LinkLocal | If TRUE, the instance is created for link-local address. Otherwise, it is not for a link-local address. |

Send a frame from the interface. If the next hop is multicast address, it is transmitted immediately. If the next hop is a unicast, and the NextHop's MAC is not known, it will perform address resolution. If some error happened, the CallBack won't be called. So, the caller must test the return value, and take action when there is an error.

[in] | IpInstance | The IP child that request the transmission. NULL if it is the IP6 driver itself. |
[in] | Packet | The packet to transmit. |
