New Revision: 331797
URL: https://svnweb.freebsd.org/changeset/base/331797

Log:
  Use an accessor function to access ifr_data.
  
  This fixes 32-bit compat (no ioctl command defintions are required
  as struct ifreq is the same size).  This is believed to be sufficent to
  fully support ifconfig on 32-bit systems.
