ssh_driver_set_information()
Request changes in the state of virtual NIC. All but OID_PNP_SET_POWER,
OID_PNP_ENABLE_WAKE_UP and OID_TCP_TASK_OFFLOAD change requests are
passed down to the underlaying NIC.
Arguments:
miniport_context - virtual NIC object
oid - change request operation identifier
info - data for change operation
info_len - data buffer length
bytes_read - how many bytes has been read from info buffer
bytes_needed - how many bytes is needed to complete the set operation
successfully
Returns:
NDIS_STATUS_SUCCESS - query completed successfully,
NDIS_STATUS_PENDING - change request completion pending,
NDIS_STATUS_RESOURCES - resource allocation for change request failed
Notes:
Default IRQL: DISPATCH_LEVEL
