We were checking that the MC (member config) was != 0
for some reason, all we need to check is that the config
has no ports, i.e. no members. Then it can be recycled.
This must be some misunderstanding.

The max VLAN number with non-4K VLAN activated is 15, and the
range is 0..15. Not 16.

The impact should be low since we by default have 4K VLAN and
thus have 4095 VLANs to play with in this switch. There will
not be a problem unless the code is rewritten to only use
16 VLANs.

While we were defining one VLAN per port for isolating the ports
the port_vlan_filtering() callback was implemented to enable a
VLAN on the port + 1. This function makes no sense, not only is
it incomplete as it only enables the VLAN, it doesn't do what
the callback is supposed to do, which is to selectively enable
and disable filtering on a certain port.

Implement the correct callback: we have two registers dealing
with filtering on the RTL9366RB, so we implement an ASIC-specific
callback and implement filering using the register bit that makes
the switch drop frames if the port is not in the VLAN member set.

The DSA documentation Documentation/networking/switchdev.rst states:

  When the bridge has VLAN filtering enabled and a PVID is not
  configured on the ingress port, untagged and 802.1p tagged
  packets must be dropped. When the bridge has VLAN filtering
  enabled and a PVID exists on the ingress port, untagged and
  priority-tagged packets must be accepted and forwarded according
  to the bridge's port membership of the PVID VLAN. When the
  bridge has VLAN filtering disabled, the presence/lack of a
  PVID should not influence the packet forwarding decision.

To comply with this, we add two arrays of bool in the RTL8366RB
state that keeps track of if filtering and PVID is enabled or
not for each port. We then add code such that whenever filtering
or PVID changes, we update the filter according to the
specification.

This hacky default VLAN setup was done in order to direct
packets to the right ports and provide port isolation, both
which we now support properly using custom tags and proper
bridge port isolation.

We can drop the custom VLAN code and leave all VLAN handling
alone, as users expect things to be. We can also drop
ds->configure_vlan_while_not_filtering = false; and let
the core deal with any VLANs it wants.

====================
Move devlink_register to be last devlink command

This is second version of patch series
https://lore.kernel.org/netdev/cover.1628599239.git.leonro@nvidia.com/

The main change is addition of delayed notification logic that will
allowed us to delete devlink_params_publish API (future series will
remove it completely) and conversion of all drivers to have devlink_register
being last commend.

The series itself is pretty straightforward, except liquidio driver
which performs initializations in various workqueues without proper
locks. That driver doesn't hole device_lock and it is clearly broken
for any parallel driver core flows (modprobe + devlink + PCI reset will
100% crash it).

In order to annotate devlink_register() will lockdep of holding
device_lock, I added workaround in this driver.

Thanks

----------------------
From previous cover letter:
Hi Dave and Jakub,

This series prepares code to remove devlink_reload_enable/_disable API
and in order to do, we move all devlink_register() calls to be right
before devlink_reload_enable().

The best place for such a call should be right before exiting from
the probe().

This is done because devlink_register() opens devlink netlink to the
users and gives them a venue to issue commands before initialization
is finished.

1. Some drivers were aware of such "functionality" and tried to protect
themselves with extra locks, state machines and devlink_reload_enable().
Let's assume that it worked for them, but I'm personally skeptical about
it.

2. Some drivers copied that pattern, but without locks and state
machines. That protected them from reload flows, but not from any _set_
routines.

3. And all other drivers simply didn't understand the implications of early
devlink_register() and can be seen as "broken".

The change of devlink_alloc() to accept device makes sure that device
is fully initialized and device_register() does nothing except allowing
users to use that devlink instance.

Such change ensures that no user input will be usable till that point and
it eliminates the need to worry about internal locking as long as devlink_register
is called last since all accesses to the devlink are during initialization.

This change fixes the following lockdep warning.

The liquidio driver is broken by design. It initialize PCI devices
in separate delayed works. It causes to the situation where device lock
is dropped during initialize and remove sequences.

That lock is part of driver/core and needed to protect from races during
init, destroy and bus invocations.

In addition to lack of locking protection, it has incorrect order of
destroy flows and very questionable synchronization scheme based on
atomic_t.

This change doesn't fix that driver but makes sure that rest of the
netdev subsystem doesn't suffer from such basic protection by adding
device_lock over devlink_*() APIs and by moving devlink_register()
to be last command in setup_nic_devices().
