Previously, NEWDEV/DELDEV notifications were emitted for new/renamed devices added to a chain or flowtable only. For user space to fully comprehend which interfaces a hook binds to, these notifications have to be sent for matching devices at hook creation time, too. This series extends the notify list to support messages for varying groups so it may be reused by the NFNLGRP_NFT_DEV messages (patch 1), adjusts the device_notify routines to support enqueueing the message instead of sending it right away (patch 2) and finally adds extra notify calls to nf_tables_commit() (patch 3).
