Function Name : LPC3xxx_MiniportInitialize
Description :
Called by the NDIS Wrapper to initialize the adapter.
0. Verify the Adapter v/s the driver
1. Create and initilize the adapter structure
2. Read and load the registry settings
3. Initialize the chip
4. Establish the link
Parameters :
PNDIS_STATUS OpenErrorStatus - Additional error status, if return value is error
PUINT MediumIndex - specifies the medium type the driver or its network adapter uses
PNDIS_MEDIUM MediumArray - Specifies an array of NdisMediumXXX values from which
MiniportInitialize selects one that its network adapter supports
or that the driver supports as an interface to higher-level drivers.
UINT MediumArraySize - Specifies the number of elements at MediumArray
NDIS_HANDLE AdapterHandle - Specifies a handle identifying the miniport’s network adapter,
which is assigned by the NDIS library
NDIS_HANDLE ConfigurationContext - Specifies a handle used only during initialization for
calls to NdisXXX configuration and initialization functions
Return Value :
NDIS_STATUS Status
