• NdisGetPhysicalAddressHigh
  Returns the high-order part of a given physical address.

• NdisGetPhysicalAddressLow
  Returns the low-order part of a given physical address.

• NdisSetPhysicalAddressHigh
  Sets the high-order part of a given physical address to a given value.

• NdisSetPhysicalAddressLow
  Sets the low-order part of a given physical address to a given value.

• NdisGetSharedDataAlignment
  Returns the preferred alignment for memory structures that can be shared by more than one processor.
