+ * External Device physical address types

+ * Currently, both MAC and IPA uController use the same size addresses
+ * and descriptors are exchanged between these two depending on the mode.
+ *
+ * Rationale: qdf_dma_addr_t is the type used internally on the host for DMA
+ *            operations. However, external device physical address sizes
+ *            may be different from host-specific physical address sizes.
+ *            This calls for the following definitions for target devices
+ *            (MAC, IPA uc).
