This does not sound like it will scale very well, as the number of tables increases. Also, at least in the DSA world, getting a table can be an expensive operation, lots of MDIO/SPI/I2C transactions. I'd prefer to be able to just get one specific table, rather than dump them all. I can however see cases when it does make sense to have an atomic, dump everything operation, where you can trust to be consistent across tables. > >Hopefully it will be more obvious when the user space patches are > >available. > > I'll ask Arkadi to send the devlink userspace patches as RFC as well. Great, thanks. Andrew
