New Revision: 339460
URL: https://svnweb.freebsd.org/changeset/base/339460
Log:
Fix a dead store.
We would fail to clear DNS search list configuration if a router
stopped specifying the DNSSL RA option. I suspect that the bug
was mostly harmless, as the RDNSS and DNSSL options are typically used
together and omitting the RDNSS option would have the same effect.
