Routine Description:

    This function is allocates the block that contains all the relavent info
    related to a given setup directory's INF files.


Arguments:

    InfPath - path to INF directory.  default is %systemroot%\inf if NULL.

    pNetCards - A pointer to a pointer that receives the allocated
        NETCARD_INF_BLOCK block allocated.  NULL if we return an error.

Return Value:

    Windows Error.

Routine Description:

    We go through all the INF files on the server to pick out the net
    cards supported and the required reg fields to send to the client.

    This function uses the FindFirstFile and SetupOpenInfFile APIs to
    enumerate all the inf files and process all net card INFs.

Arguments:

    pNetCards - A pointer to NETCARD_INF_BLOCK block allocated.  Contains all
       the persistant info required for the netcards.

Return Value:

    Windows Error.

    )
/*++

Routine Description:

    This function uses the SetupXxxx APIs to process a given INF file for
    all net card drivers.  Each INF file is first parsed for the MANUFACTURERS
    section.  This section contains all the section keys that contain all
    the devices.  We then enumerate all the devices in each manufacturer's
    section and call off to ParseCardDetails to add it to our list.

    As an example, the net557.inf file looks like this :

    [Manufacturer]
    %Intel%     = Intel
    %ATI%       = ATI
    %Compaq%    = Compaq
    %HPTX%      = HPTX
    %IBM%       = IBM
    %Microdyne% = Microdyne
    %Samsung%   = Samsung

    and the [ATI] section looks like this :

    [ATI]
    ; DisplayName            Section        DeviceID
    %AT2560B.DeviceDesc%   = AT2560B.ndi,   PCI\VEN_1259&DEV_2560&REV_01
    %AT2560C.DeviceDesc%   = AT2560C.ndi,   PCI\VEN_8086&DEV_1229&SUBSYS_25601259
    %AT2560CFX.DeviceDesc% = AT2560CFX.ndi, PCI\VEN_8086&DEV_1229&SUBSYS_25611259

Arguments:

    pNetCards - A pointer to NETCARD_INF_BLOCK block allocated.  Contains all
       the persistant info required for the netcards.

    InfHandle - handle open to INF file, guarenteed to be net driver

    InfFileName - wide form of relative file name we have open.

Return Value:

    Windows Error.  We stop processing altogether at ERROR_NOT_ENOUGH_MEMORY

Routine Description:

    This function uses the SetupXxxx APIs to process an INF file for a given
    driver instance.  We parse the inf file for the registry section given.
    Note that this is a different format than the extended install section.

    Here's an example of the lines we parse :

    HKR, Ndi\params\NumCoalesce,    type,       0, "int"
    HKR, ,                          MsPciScan,  0, "2"

    Note that we skip everything in the Ndi registry area.

Arguments:

    pNetCards - A pointer to NETCARD_INF_BLOCK block allocated.  Contains all
       the persistant info required for the netcards.

    InfHandle - handle open to INF file, guarenteed to be net driver

    InfFileName - wide form of relative file name we have open.

    pEntry - entry for which to get registry settings for

    SectionToParse - what section in the INF do we start with

Return Value:

    Windows Error.  We stop processing altogether at ERROR_NOT_ENOUGH_MEMORY

Routine Description:

    This function uses the SetupXxxx APIs to process an INF file for a given
    driver instance.  We parse the inf file for the registry section given.
    Note that this is a different format than the extended install section.

    Here's an example of the lines we parse :

    CopyFiles = @elnk90.sys
    CopyFiles = e100b.CopyFiles

    [e100b.CopyFiles]
    e100bnt.sys,,,2
    n100.sys,n100nt.sys,,2

Arguments:

    pNetCards - A pointer to NETCARD_INF_BLOCK block allocated.  Contains all
       the persistant info required for the netcards.

    InfHandle - handle open to INF file, guarenteed to be net driver

    InfFileName - wide form of relative file name we have open.

    pEntry - entry for which to get registry settings for

    SectionToParse - what section in the INF do we start with

Return Value:

    Windows Error.  We stop processing altogether at ERROR_NOT_ENOUGH_MEMORY
