if NULL.
@param[in] IpInstance The IP6 child that issues the transmission. It is
NULL if the packet is from the system.
@param[in] Packet The user data to send, excluding the IP header.
@param[in] Head The caller supplied header. The caller should set
the following header fields: NextHeader, HopLimit,
Src, Dest, FlowLabel, PayloadLength. This function
will fill in the Ver, TrafficClass.
@param[in] ExtHdrs The extension headers to append to the IPv6 basic

@retval EFI_NOT_FOUND There is no route to the destination.
@retval EFI_SUCCESS The packet successfully transmitted.
@retval EFI_OUT_OF_RESOURCES Failed to finish the operation due to lack of
resources.
