New Revision: 205312
URL: http://svn.freebsd.org/changeset/base/205312
Log:
Make sure the snmp_pf module will first refresh its entires if necessary,
then find a specific entry, and get the requested value. So far, it found
the specific entry, refreshed the entry list if necessary, and got the
requested value from the found entry. The problem is that refreshing nukes
all old entries and replaces them with new ones and the obtained entry
pointer was no longer valid after the refresh.
