New Revision: 257078
URL: http://svnweb.freebsd.org/changeset/base/257078

Log:
  Fix panic in the tap driver when a tap and vmnet interface were
  created after each other e.g.
  
   ifconfig tap0
   ifconfig vmnet0
   <panic>
  
  Appears to be a cut'n'paste error from the tap code to the vmnet
  code where the name string wasn't updated in the call to make_dev().
