Differences in Calls to NdisXxx Functions

A call manager calls a different set of call manager functions than an MCM driver. A call manager calls NdisCm_Xxx_ functions, and an MCM driver calls NdisMCm_Xxx_ functions.

An MCM driver does not call the NdisCo_Xxx_ functions that both connection-oriented clients and call managers call. Instead, an MCM driver calls the following comparable NdisMCm_Xxx_ functions:

• NdisMCmCreateVc instead of NdisCoCreateVc

• NdisMCmDeleteVc instead of NdisCoDeleteVc

• NdisMCmOidRequest instead of NdisCoOidRequest

• NdisMCmOidRequestComplete instead of NdisCoOidRequestComplete

An MCM driver does not require a call that is comparable to NdisCoSendNetBufferLists, because the send interface between the call manager and the miniport driver is internal to an MCM driver and therefore opaque to NDIS.
