Subject: tests: Add a simple test suite for --echo option
X-Git-Tag: v0.8~90
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ba801025d639248e13ca662ed5068beaa80271c2;p=thirdparty%2Fnftables.git

tests: Add a simple test suite for --echo option

The fancy thing about this is that it uses the actual echo output to
undo the changes to the rule set.
