 Adding options IWN_DEBUG produces
 
 ../../../../dev/pci/if_iwn.c:190:1: error: "IWN_DEBUG" redefined
 
 during make depend.
 
 IWN_DEBUG is already #define'ed in if_iwn.c, but the variable iwn_debug is
 set to 0. Looks like the right thing is to set it non-zero, e.g., to 5 for
 the maximum amount of chatter, by changing line 195 to
 
 int iwn_debug = 5;
 
 I will give this a try.
