   5) Investigate problems with PCI Message Signalled Interrupts (MSI).
 
-  6) Add port multiplier support (intermediate)
+  6) Cache frequently-accessed registers in mv_port_priv to reduce overhead.
+
+  7) Fix/reenable hot plug/unplug (should happen as a side-effect of (2) above).
 
   8) Develop a low-power-consumption strategy, and implement it.
