This patch series adds support for devlink commands batching. The first
just removes a requirement to have declared 'resolve_hosts' variable in
any command that use any function implemented in utils.c (it is really
confusing to see this declaration in utils like bridge or devlink).

The patch declares single common instance of resolve_hosts directly in utils.c so the existing ones can be removed (the same approach that is used for timestamp_short).

Leon, we should really do things in a way they are currently done and used. Batching is implemented in "ip" for a long time. It makes perfect sense to have one command line per line of the batch file. In contrary, json output sounds really odd in this case. With json, there is no relation to ordinary ip command line params. Or do you want to extend it to accept json as well? ^ permalink raw reply [flat|nested] 13+ messages in thread

Yes, I wanted to add new field - "cmd", and whole logic to parse JSON to properly rebuild command from that with right parameters and device name. However, most probably, I'll never finish it near future, so in meanwhile I will provide the same batch format as Ivan proposed.
