// Binding/unbinding to an NDIS device:
|
||
|
|
//
|
||
|
|
// On processing a BindAdapter call from NDIS, we set up a binding
|
||
|
|
// to the specified NDIS device (miniport). This binding is
|
||
|
|
// torn down when NDIS asks us to Unbind by calling
|
||
|
|
// our UnbindAdapter handler.
|
||
|
|
//
|
||
|
|
// Receiving data:
|
||
|
|
//
|
||
|
|
// While an NDIS binding exists, read IRPs are queued on this
|
||
|
|
// structure, to be processed when packets are received.
|
||
|
|
// If data arrives in the absense of a pended read IRP, we
|
||
|
|
// queue it, to the extent of one packet, i.e. we save the
|
||
|
|
// contents of the latest packet received. We fail read IRPs
|
||
|
|
// received when no NDIS binding exists (or is in the process
|
||
|
|
// of being torn down).
|
||
|
|
//
|
||
|
|
// Sending data:
|
||
|
|
//
|
||
|
|
// Write IRPs are used to send data. Each write IRP maps to
|
||
|
|
// a single NDIS packet. Packet send-completion is mapped to
|
||
|
|
// write IRP completion. We use NDIS 5.1 CancelSend to support
|
||
|
|
// write IRP cancellation. Write IRPs that arrive when we don't
|
||
|
|
// have an active NDIS binding are failed.

// Reference count:

//

// OPEN_DEVICE ioctl (goes away on processing a Close IRP)
