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.
