 Because there were so many net related commits in RELENG_8
 recently I rebuilt my system today.
 
 It appears that the system now doesn't panic any more. If at
 all the connection, now works for a maximum of 10 seconds,
 though.
 
 I have to reload the if_wpi and wpifw modules to get it
 running again (for another 10 seconds).
 
 This is what ttyv0 looks like, the beacon misses start
 after a couple of seconds:

 I also recognized that wlan0 always lists "txpower 0",
 even if I try to set it manually (txpowermax is 50.0).
