svn commit: r249000 - head/sys/dev/ath

[Adrian Chadd]

Author: adrian

New Revision: 249000
URL: http://svnweb.freebsd.org/changeset/base/249000

Log:
  Mark a couple of places where I think the dmamap isn't being unmapped
  before the TX path is being aborted.
  
  Right now it's in the TDMA code and I can live with that; but it really
  should get fixed.
  
  I'll do a more thorough audit of this code soon.
