+ * PF<->VF Messaging
+ * The PF has an array of 32-bit PF2VF registers, one for each VF.  The
+ * PF can access all these registers; each VF can access only the one
+ * register associated with that particular VF.
+ *
+ * The register functionally is split into two parts:
+ * The bottom half is for PF->VF messages. In particular when the first
+ * bit of this register (bit 0) gets set an interrupt will be triggered
+ * in the respective VF.
+ * The top half is for VF->PF messages. In particular when the first bit
+ * of this half of register (bit 16) gets set an interrupt will be triggered
+ * in the PF.
+ *
+ * The remaining bits within this register are available to encode messages.
+ * and implement a collision control mechanism to prevent concurrent use of
+ * the PF2VF register by both the PF and VF.
