New Revision: 190151
URL: http://svn.freebsd.org/changeset/base/190151

Log:
  Call the interface's if_ioctl from ifioctl(), if the protocol didn't
  handle the ioctl.  There are other paths that already call it, but this
  allows for a non-interface socket (like AF_LOCAL which ifconfig now
  uses) to use a broader class of interface ioctls.
