Between legacy mode and switchdev mode, only two fields are changed,
vlan_tag and flow action.
Hence to avoid duplicte code between two modes, introduce and and use
helper function to configure allowed VLAN rule.
While at it, get rid of duplicate debug message.

From: Parav Pandit <parav@mellanox.com>
Currently esw_enable_vport() does vport check for zero to enable drop
counters regardless of execution on ECPF/PF.
While esw_disable_vport() considers such scenario.
To keep consistency across code for checking for manager_vport,
introduce and use mlx5_esw_is_manager_vport() to check if a specified
vport is eswitch manager vport or not.

fdb_table is used for both legacy and offloads mode.
It was incorrect to comment that fdb_table is legacy specific.
Hence, fix the comment to reflect that fdb_table is used in legacy and
offloads mode.

Metadata fields are offload mode specific.

To improve code readability, move legacy drop counters and droup rule
under legacy structure.
While at it,
(a) prefix drop flow counters helper with legacy_.
(b) nullify the rule pointers only if they were valid.

From: Parav Pandit <parav@mellanox.com>
When eswitch is disabled, vport event handler is unregistered.
This unregistration already synchronizes with running EQ event handler
in below code flow.
mlx5_eswitch_disable()
mlx5_eswitch_event_handlers_unregister()
mlx5_eq_notifier_unregister()
atomic_notifier_chain_unregister()
synchronize_rcu()
notifier_callchain
eswitch_vport_event()
queue_work()
Additionally vport->enabled flag is set under state_lock during
esw_enable_vport() but is not read under state_lock in
(a) esw_disable_vport() and (b) under atomic context
eswitch_vport_event().
It is also necessary to synchronize with already scheduled vport event.
This is already achieved using below sequence.
mlx5_eswitch_event_handlers_unregister()
[..]
flush_workqueue()
Hence,
(a) Remove vport->enabled check in eswitch_vport_event() which
doesn't make any sense.
(b) Remove redundant flush_workqueue() on every vport disable.
(c) Keep esw_disable_vport() symmetric with esw_enable_vport() for
state_lock.

In subsequent patch, esw_enable_vport() could fail and return error.
Prepare code to handle such error.

Introduce and use per vport ACL tables creation and destroy APIs, so that
subsequently patch can use them during enabling/disabling a vport in
unified way for legacy vs offloads mode.

It is better to create/destroy ACL related drop counters where the actual
drop rule ACLs are created/destroyed, so that ACL configuration is self
contained for ingress and egress.

Currently legacy mode enables ACL while enabling vport, while offloads
mode enable ACL when moving to offloads mode.
Bring consistency to both modes by enabling/disabling ACL when
enabling/disabling a vport.
It also eliminates creating ingress ACL table on unused ECPF vport in
offloads mode.

Drop, untagged, spoof check and untagged spoof check flow groups are
limited to legacy mode only.
Therefore, following refactoring is done to
(a) improve code readability
(b) have better code split between legacy and offloads mode
1. Move legacy flow groups under legacy structure
2. Add validity check for group deletion
3. Restrict scope of esw_vport_disable_ingress_acl to legacy mode
4. Rename esw_vport_enable_ingress_acl() to
esw_vport_create_ingress_acl_table() and limit its scope to
table creation
5. Introduce legacy flow groups creation helper
esw_legacy_create_ingress_acl_groups() and keep its scope to legacy mode
6. Reduce offloads ingress groups from 4 to just 1 metadata group
per vport
7. Removed redundant IS_ERR_OR_NULL as entries are marked NULL on free.
8. Shortern error message to remove redundant 'E-switch'

Currently on ECPF, metadata is enabled on the ECPF vport = 0xfffe
(manager vport).
Metadata when supported, must be enabled on own vport which is
used to pass metadata to vport of NIC Rx Flow Table.
Due to this error, traffic tagged by ingress ACL is not processed
correctly at NIC rx flow table level which is supposed to work
on metadata tag.
Hence, instead of working on eswitch manager vport, always working on
eswitch own vport regardless of PF or ECPF.
Given that mlx5_eswitch_query/modify_esw_vport_context() is used to
access other vport in legacy mode and own vport settings in switchdev mode,
extend low level API to explicitly specify other_vport.
Fixes: c1286050cf47 ("net/mlx5: E-Switch, Pass metadata from FDB to eswitch manager")

Instead of deciding a given device is virtual function or
not based on a device is PF or not, use already defined
MLX5_COREDEV_VF by introducing an helper API mlx5_core_is_vf().
This enables to clearly identify PF, VF and non virtual functions.
