The miniport driver sets the NDIS_SRIOV_CAPS_PF_MINIPORT flag in the SriovCapabilities member to report SR-IOV capabilities. Starting with NDIS 6.30, the miniport driver sets the Revision member of Header to NDIS_SRIOV_CAPABILITIES _REVISION_1 and the Size member to NDIS_SIZEOF_SRIOV_CAPABILITIES_REVISION_1. For example, a disk device that uses Random Access Memory (RAM) to store its data is commonly called a RAMDISK. The driver sets the Type member of Header to NDIS_OBJECT_TYPE_DEFAULT. A virtual miniport driver is appropriate when it completely simulates one or more devices, or it has no hardware of its own to control but it communicates with another device using its device driver as a transport for I/O requests. The miniport driver initializes the Header member. The VF miniport driver reports the SR-IOV hardware capabilities of the underlying virtual network adapter through an NDIS_SRIOV_CAPABILITIES structure that is initialized in the following way: For more information about these keywords, see Standardized INF Keywords for SR-IOV. Unlike the PF miniport driver, the VF miniport driver must not be installed with the SR-IOV standardized keywords and must not attempt to read these keywords. If possible, the driver must initialize as a PF driver as described in Initialization Sequence for PF Miniport Drivers. In this case, the miniport driver must not initialize as a VF driver. I don't remember seeing this on the list before, and it suddenly seems to have appeared.

If MiniportInitializeEx failed, MiniportInitializeEx must release all resources that it allocated before it returns and the adapter returns to the Halted state.If the partition type is reported as NdisHypervisorPartitionMsHvParent, the miniport driver is running in the Hyper-V parent partition that is attached to the PF on the adapter. Okay, so I was browsing through the adapter settings in windows 7 and came across a Wiresless Conenction 2 which is a Microsoft Virtual WiFi Miniport Adapter. For more information, see Halting a Miniport Adapter. If MiniportInitializeEx returns NDIS_STATUS_SUCCESS, the driver should release all the resources for the adapter in the MiniportHaltEx function. In the system tray it shows the Wi-fi icon and it works for say 10 hours then it disconnects. I have been dealing with this problem for a few months. For more information, see Starting a Miniport Adapter. Microsoft Wi-Fi Direct Virtual Adapter is Evil Tonight I finally have confirmation that my Ralink RT5390 802.11 b/g/n Wi-Fi Adapter is not bad. NDIS can call the MiniportRestart function to transition the adapter to the Running state. The following list contains the default encryption settings for the Microsoft L2TP/IPSec virtual private network (VPN) client for earlier version.

Applies to: Windows 10 - all editions Original KB number: 325158. NET_BUFFER and NET_BUFFER_LIST pools (see Miniport Driver Send and Receive Operations).Īfter MiniportInitializeEx returns successfully, the adapter is in the Paused state. This article describes the default encryption settings for the Microsoft L2TP/IPSec virtual private network (VPN) client. Typically, MiniportInitializeEx allocates adapter-specific resources in the following order: The miniport driver specifies the adapter attributes in the NDIS_MINIPORT_ADAPTER_ATTRIBUTES structure that MiniportInitializeEx passes to NdisMSetMiniportAttributes. The time-out interval for calling its MiniportCheckForHangEx function.A pointer to a driver-allocated context area.Obtains information about the hardware resources for the adapter.Ĭalls the NdisMSetMiniportAttributes and provides the following attributes that are associated with the adapter: Obtains configuration information for the adapter. The adapter is in the Initializing state.Ī miniport driver typically performs the following tasks in MiniportInitializeEx: Until MiniportInitializeEx returns, NDIS submits no requests for the adapter being initialized.

For more information about miniport driver initialization, see Initializing a Miniport Driver. NDIS can call MiniportInitializeEx at any time after the driver is initialized. NDIS calls the miniport driver's MiniportInitializeEx function to initialize an adapter for network I/O operations. These are useful if you need to extend a wireless connection or provide WiFi for other. It is a virtual adapter that allows Windows to split a network in two, either to act as a wireless bridge or WiFi hotspot. Subsequently, the Plug and Play (PnP) manager sends NDIS a Plug and Play IRP to start the device. The Microsoft virtual WiFi miniport adapter has been around since Windows 7 and features on laptops and mobile devices with WiFi cards. When a networking device becomes available, the system loads the required NDIS miniport driver, if it is not already loaded.
