OID_GEN_TRANSPORT_HEADER_OFFSET (Windows CE 5.0)
This object indicates the size of additional headers for packets that a particular transport sends and receives.
A transport informs miniport and other layered drivers of this header size; these drivers can then use this information when processing packets. For example, a driver could use the sub-layer header size obtained from the transport to locate the beginning of higher layer information in packets, such as the start of the IP protocol header; the driver could then parse and adjust the fields of the IP protocol header as appropriate. Transports use a TRANSPORT_HEADER_OFFSET structure to indicate this header size.
This object is optional for miniport and other layered drivers. Because this object is optional, drivers are not required to respond to requests that transports make using this object.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: Ntddndis.h.
