Subject: Simplify the packets in the formerr system test
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=be4f0849f25e267af5e4ca137245eae6bba1abe0;p=thirdparty%2Fbind9.git

Simplify the packets in the formerr system test

Normalize the message ID to 0 and the TTL of records to 1 unless
required (OPT and UPDATE records require TTL=0).
