svn commit: r187328 - head/sys/net

[Qing Li]

Author: qingli

New Revision: 187328
URL: http://svn.freebsd.org/changeset/base/187328

Log:
  The RTF_LLINFO was revived unconditionally, but within the kernel the
  check on the sysctl argument value being RTF_LLINFO is conditioned on
  the COMPAT_ROUTE_FLAGS kernel option. This mismatch caused the L2
  table retrieval failure, and the arp/ndp -an command displays empty L2
  tables.
