Routine Description:
|
|
|
|
The MpQueryProtocolInformation process a Query request for
|
|
NDIS_OIDs that are specific to a binding about the MAC. Note that
|
|
some of the OIDs that are specific to bindings are also queryable
|
|
on a global basis. Rather than recreate this code to handle the
|
|
global queries, I use a flag to indicate if this is a query for the
|
|
global data or the binding specific data.
|
|
|
|
Arguments:
|
|
|
|
Adapter - a pointer to the adapter.
|
|
|
|
Oid - the NDIS_OID to process.
|
|
|
|
Return Value:
|
|
|
|
The function value is the status of the operation.
