devlink: add a command to set notification filter and use it for multicasts
Currently the user listening on a socket for devlink notifications gets always all messages for all existing instances, even if he is interested only in one of those. That may cause unnecessary overhead on setups with thousands of instances present. User is currently able to narrow down the devlink objects replies to dump commands by specifying select attributes. Allow similar approach for notifications. Introduce a new devlink NOTIFY_FILTER_SET which the user passes the select attributes. Store these per-socket and use them for filtering messages during multicast send. Signed-off-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
