Message-ID: <20250630164222.712558-5-sdf@fomichev.me>

Subject: [PATCH net-next v2 4/8] net: s/dev_pre_changeaddr_notify/netif_pre_changeaddr_notify/
Commit cc34acd577f1 ("docs: net: document new locking reality")
introduced netif_ vs dev_ function semantics: the former expects locked
netdev, the latter takes care of the locking. We don't strictly
follow this semantics on either side, but there are more dev_xxx handlers
now that don't fit. Rename them to netif_xxx where appropriate.
netif_pre_changeaddr_notify is used only by ipvlan/bond, so move it into
NETDEV_INTERNAL namespace.
