 Note that wpa_supplicant continues to run on X session exit, and all that
 is needed is a "ifconfig iwn0 up" - the mystery is what is bringing it
 down.
 
 Today's experiment:
 
 Boot up laptop (xdm=YES in rc.conf)
 ctrl-alt-f1
 login as root
 wpa_supplicant -B -i iwn0 -c ...
 dhcpcd -4L iwn0
 ping www.netbsd.org (successful)
 
 ctrl-alt-f8 for xdm login
 ping www.netbsd.org (successful)
 logout
 
 ctrl-alt-f1
 
 see iwn0: fatal firmware error
 firmwre error log:
   error type = "UNKNOWN" (0x000022CE)
 
 ifconfig shows interface is down.
 
 
 ifconfig iwn0 up
 ping www.netbsd.org (successful)
 
 
 wpa_supplicant and dhcpcd were not started within X.
