Some APs broadcast WPS IE frames with totally broken data. Ifconfig's printwpsie() loops through WPS frames printing the attributes out; if the frame's data is bad, printwpsie() can end up looking at out-of-bounds addresses causing ifconfig to bus error. Thanks to Takashi Inoue at Nihon U for his efforts in debugging this. PR: bin/217312 Submitted by: fbsd@opal.com MFC after: 1 week
