 this is a well known issue with iwi(4) in netbsd-3.  this and other
 related bugs are fixed in -current for some time now.  the problem is
 that the iwi(4) in HEAD is quite different to the one on netbsd-3,
 including major net80211 update.
 
 the proper long term fix would be to backport net80211 changes and all
 the related wireless drivers changes to netbsd-3, for 3.1, ideally.
 
 feel free to help.
 
 regards,
 
 (status of this PR should be probably changed to "suspended")
