+ * 12/10/99 - Alpha Release 0.1.0
+ * First release to the public
+ * 03/03/00 - Merged to kernel, indented -kr -i8 -bri0, fixed some missing
+ * malloc free checks, reviewed code. <alan@redhat.com>
+ *
+ * To Do:
+ *
+ * 1) Test Network Monitor Mode
+ * 2) Add auto reset logic on adapter errors
+ * 3) Test with varying options
+ *
+ * If Problems do Occur
+ * Most problems can be rectified by either closing and opening the interface
+ * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
+ * if compiled into the kernel).
