NdisReadRegisterUshort is called by the miniport driver to read a USHORT from a memory-mapped device register.
void NdisReadRegisterUshort( Register, Data );
Pointer to the memory-mapped register. This virtual address must fall within a range returned by an initialization-time call to NdisMMapIoSpace.
Pointer to the caller-supplied variable in which this function returns the USHORT read from Register .
If a driver calls this function, a NIC's device registers must be mapped to noncached memory during driver initialization.
