 This is a list of things that need to be done to get this driver out of the
 staging directory.
+
+- Implement the gasket framework's functionality through UIO instead of
+  introducing a new user-space drivers framework that is quite similar.
+
+  UIO provides the necessary bits to implement user-space drivers. Meanwhile
+  the gasket APIs adds some extra conveniences like PCI BAR mapping, and
+  MSI interrupts. Add these features to the UIO subsystem, then re-implement
+  the Apex driver as a basic UIO driver instead (include/linux/uio_driver.h)
+
 - Document sysfs files with Documentation/ABI/ entries.
+
 - Use misc interface instead of major number for driver version description.
+
 - Add descriptions of module_param's
+
 - apex_get_status() should actually check status.
+
 - "drivers" should never be dealing with "raw" sysfs calls or mess around with
   kobjects at all. The driver core should handle all of this for you
   automaically. There should not be a need for raw attribute macros.

           This option adds a `CHECKSUM' target, which can be used in the iptables mangle
-          table.
+          table to work around buggy DHCP clients in virtualized environments.
 
-          You can use this target to compute and fill in the checksum in
-          a packet that lacks a checksum.  This is particularly useful,
-          if you need to work around old applications such as dhcp clients,
-          that do not work well with checksum offloads, but don't want to disable
-          checksum offload in your device.
+          Some old DHCP clients drop packets because they are not aware
+          that the checksum would normally be offloaded to hardware and
+          thus should be considered valid.
+          This target can be used to fill in the checksum using iptables
+          when such packets are sent via a virtual network device.
 
           To compile it as a module, choose M here.  If unsure, say N.
