The EvtVmbChannelRestorePacket callback function is invoked when the virtualization service provider (VSP) server endpoint must restore the state associated with a packet object.
Channel [in]The channel on which the packet arrives.
LibBuf [in]Pointer to packet object state internal to the Kernel Mode Client Library (KMCL).
LibBufSize [in]Size of the LibBuf parameter, in bytes.
SaveBuf [in]Pointer to transaction state specific to the VSP.
SaveBufSize [in]Size of the SaveBuf parameter, in bytes.
EvtVmbChannelRestorePacket returns a status code.
The VmbServerChannelInitSetSaveRestorePacketCallbacks function sets a callback function for restoring packets for each channel.
In order to restore an in-flight packet object, the VSP must allocate a new packet by using the VmbPacketAllocate function. The VSP restores the packet to the previous state by passing LibBuf and LibBufSize to the VmbPacketRestore function. If the VSP provided any internal state for the transaction in the EvtVmbChannelSavePacket callback function, then this is provided in SaveBuf, and restored by the VSP.
