Print the number of allocated set elements if the set provided an upper size limit and there is at least one element. Example: table ip t { set s { type ipv4_addr size 65535 # count 1 flags dynamic counter elements = { 1.1.1.1 counter packets 1 bytes 11 } } ... First patch prepares python tests to skip the new debug information coming with updated libnftnl. This is needed to avoid a (large) update of all the existing / recorded dumpinfo. Second patch dumps set debug info with --debug=netlink flag, i.e.: nft --debug=netlink list ruleset family 2 s t 0 backend nft_set_rhash_type family 2 __set0 t 3 size 3 backend nft_set_hash_fast_type count 3 (actual ruleset omitted) Third patch includes the new 'size <value> # count <value>' output. Last patch fixes shell tests: Dumps are updated with the new format (not too many changes, the change is only needed for sets that have both 'size' set and are not empty at the end of the test). For old kernels (missing COUNT attribute), the dumps will be postprocessed after failure to strip '# count', then re-diff happens.
