MINIPORT_WDI_TX_PEER_BACKLOG callback function

The MiniportWdiTxPeerBacklog handler function is issued when a paused peer has a change in backlog state. This can happen when WDI receives a send request or as a result of an NdisWdiTxReleaseFrameIndication. It is also issued on an NdisWdiTxSendPauseIndication for affected peers to notify the IHV miniport of the backlog states of those peers.

This is a WDI miniport handler inside NDIS_MINIPORT_WDI_DATA_HANDLERS.

This request is never made when TargetPriorityQueueing is set to true.

Note  You must declare the function by using the MINIPORT_WDI_TX_PEER_BACKLOG type. For more information, see the following Examples section.
