-/**
- * struct vmbus_channel_interface - Contains member functions for vmbus channel
- * @Open:      Open the channel
- * @Close:     Close the channel
- * @SendPacket:        Send a packet over the channel
- * @SendPacketPageBuffer:      Send a single page buffer over the channel
- * @SendPacketMultiPageBuffer: Send a multiple page buffers
- * @RecvPacket:        Receive packet
- * @RecvPacketRaw:     Receive Raw packet
- * @EstablishGpadl:    Set up GPADL for ringbuffer
- * @TeardownGpadl:     Teardown GPADL for ringbuffer
- * @GetInfo:   Get info about the channel
- *
- * This structure contains function pointer to control vmbus channel
- * behavior. None of these functions is externally callable, but they
- * are used for normal vmbus channel internal behavior.
- * Only used by Hyper-V drivers.
