New Revision: 192043
URL: http://svn.freebsd.org/changeset/base/192043

Log:
  ifp->if_softc is managed entirely by the driver.  We never set it to
  NULL or change it.  We initialize it before we set if_ioctl.  It can
  therefore never be NULL, and most other drivers don't bother with this
  sanity check.
