examples: XML parsing examples
Some code snipplets to add tables/chain/rules using the XML representation.
The examples contains:
* A binary to parse/add the object using libnftables.
* A shellscript to easily call that binary, doing some tests.
* table/chain/rule sample XML file.
I included my name in new files, but I don't know if this is correct. Please let me know.
Instructions:
$ cd examples/ ; make nft-table-xml-add
# cd test/ ; ./nft-table-xml-add.sh
NOTE: Some kernel changes are required to allow reinsert exactly what is printed (handle handling, flags..)
