svn commit: r257947 - head/sys/dev/iwn

[Adrian Chadd]

New Revision: 257947
URL: http://svnweb.freebsd.org/changeset/base/257947

Log:
  Send EAPOL frames at the management rate, not the data rate.
  
  Without this, a far away station with low signal strength would
  associate using the management rate (by default the lowest rate)
  and then the EAPOL frames would go out at the current AMRR best
  guess.  This would result in association failing authentication.
  
  Tested:
  
  * Intel 5100, STA
  * Intel 2230, STA
