Structure Description:

    This structure defines the information published by networking devices.

Members:

    Version - Stores the table version. Future revisions will be backwards
        compatible. Set to NETWORK_DEVICE_INFORMATION_VERSION.

    Flags - Stores a bitfield of flags describing the network device. See
        NETWORK_DEVICE_FLAG_* definitions.

    Domain - Stores the socket network domain for which this information is
        valid. Network devices may be active on more than network domain
        simultaneously (IPv4 and IPv6 for example). The caller sets this to
        request information about a given network domain's configuration.

    ConfigurationMethod - Stores the method used to configure the address of
        this device.

    Address - Stores the network address of the link.

    Subnet - Stores the network subnet mask of the link.

    Gateway - Stores the default gateway network address for the link.

    DnsServer - Stores an array of network addresses of Domain Name Servers
        to try, in order.

    DnsServerCount - Stores the number of valid DNS servers in the array.

    PhysicalAddress - Stores the physical address of the link.

    LeaseServerAddress - Stores the network address of the server who provided
        the network address if it is a dynamic address.

    LeaseStartTime - Stores the time the lease on the network address began.
        This is only valid for dynamic address configuration methods.

    LeaseEndTime - Stores the time the lease on the network address ends. This
        is only valid for dynamic address configuration methods.

    devices.

Members:

    Version - Stores the table version. Future revisions will be backwards

    Flags - Stores a bitfield of flags describing the 802.11 network device.
        See NETWORK_80211_DEVICE_FLAG_* for definitions.

    PhysicalAddress - Stores the physical address of the link.

    Bssid - Stores the BSSID of access point to which the device is associated,
        if applicable.

    Ssid - Stores the null-terminated SSID of the associated network.

    Channel - Stores the channel on which the network operates.

    MaxRate - Stores the maximum rate supported by the wireless network, in
        megabits per second.

    Rssi - Stores the received signal strength indication value for the BSS.

    PairwiseEncryption - Stores the pairwise encryption method used for the
        network connection.

    GroupEncryption - Stores the group encryption method used for the network
        connection.
