This routine checks to see is this adapter needs to be reset, and if it

we might use this right now, but I'm sure that there will be.
Arguments:
MiniportAdapterContext - AdapterContext that is given to the wrapper in
NdisMSetAttributes call. Is our AdapterCB.
Return Values:
TRUE - Reset Adapter
FALSE - Don't reset adapter

Routine Name:
NdisWanInitialize
Routine Description:
This routine is called after NdisWan registers itself as a Miniport driver.
It is responsible for installing NdisWan as a Miniport driver, creating
adapter control blocks for each adapter NdisWan exposes (should only be 1),
and initializing all adapter specific variables
Arguments:
OpenErrorStatus - Returns information about the error if this function
returns NDIS_STATUS_OPEN_ERROR. Used for TokenRing.
SelectedMediumIndex - An index into the MediumArray that specifies the
medium type of this driver. Should be WAN or 802.3
MediumArray - An array of medium types supported by the NDIS library
MediumArraySize - Size of the medium array
MiniportAdapterHandle - Handle assigned by the NDIS library that defines
this miniport driver. Used as handle in subsequent
calls to the NDIS library.
WrapperConfigurationContext - Handle used to read configuration information
from the registry
Return Values:
NDIS_STATUS_ADAPTER_NOT_FOUND
NDIS_STATUS_FAILURE
NDIS_STATUS_NOT_ACCEPTED
NDIS_STATUS_OPEN_ERROR
NDIS_STATUS_RESOURCES
NDIS_STATUS_UNSUPPORTED_MEDIA
