Windows 7/Windows CE NDIS6.2 Miniport Wi-Fi Driver


In Windows, drivers for network adapters are implemented as NDIS Miniport drivers. This driver communicates with its NIC and with higher-level drivers (filter drivers, intermediate drivers and protocol drivers) through the NDIS library. It also exports a set of Miniport handler functions, which are used by NDIS layer to communicate with Miniport driver.
