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. We care only
about driver-visible APIs, don't touch stack-internal routines.
This is part 1, I'm considering following up with these (haven't looked
deep, maybe the ones that are frequently used are fine to keep):
* dev_get_tstats64 dev_fetch_sw_netstats
* dev_xdp_prog_count,
* dev_add_pack dev_remove_pack dev_remove_pack
* dev_get_iflink
* dev_fill_forward_path
* dev_getbyhwaddr_rcu dev_getbyhwaddr dev_getfirstbyhwtype
* dev_valid_name dev_valid_name
* dev_forward dev_forward_skb
* dev_queue_xmit_nit dev_nit_active_rcu
* dev_pick_tx_zero
Sending this out to get a sense of direction :-)
v3:
- move MODULE_IMPORT_NS closer to other module metadata (Willem)
- add MODULE_IMPORT_NS to bridge (build bot)
- add ops lock assert where appropriate (Willem)
- netif_close_many - calls __dev_close_many which has an assert
- netif_set_threaded - already has an assert
- netif_get_flags - READ_ONCE, does not need any locks
- netif_set_mtu_ext - added ops lock assert, updated the doc
- netif_get_mac_address - uses dev_addr_sem
- netif_get_port_parent_id - needs only rtnl?
- netif_get_stats - uses other mechanisms (seqlock)
v2:
- move a bunch of symbols into NETDEV_INTERNAL (Willem)
- netif_close_many
- __netif_set_mtu
- netif_pre_changeaddr_notify
- netif_get_mac_address
- keep more info in the individual patches' commit message (Willem)

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.

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_set_mtu is used only by bond, so move it into
NETDEV_INTERNAL namespace.

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.
Note that one dev_set_threaded call still remains in mt76 for debugfs file.

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_close_many is used only by vlan/dsa and one mtk driver, so move it into
NETDEV_INTERNAL namespace.

This one fires, should it be ops-locked?

TBH dev_get_stats() is neither locked or unlocked.
Procfs calls it with just rcu lock. I'd skip this patch.

At the risk of annoying you I'd suggest adding a Return: statement
while you touch these kdocs. Here are some popular phrasings:
* Return: 0 on success, or a negative error code on failure
* Return: 0 on success, -errno on failure.
* Return: 0 on success, -errno otherwise.

LGTM, thanks for cleaning this up.
I'm not gonna send review tags, cause I'd have to strip them if I end
up applying these..
