Since commit 2a2cb4c6c181 ("ice: replace ice_vf_recreate_vsi() with
ice_vf_reconfig_vsi()") VF VSI is only reconfigured instead of
recreated. The context configuration from previous setting is still the
same. If any of the config needs to be cleared it needs to be cleared
explicitly.
Previously there was assumption that port vlan will be cleared
automatically. Now, when VSI is only reconfigured we have to do it in the
code.
Not clearing port vlan configuration leads to situation when the driver
VSI config is different than the VSI config in HW. Traffic can't be
passed after setting and clearing port vlan, because of invalid VSI
config in HW.
Example reproduction:
> ip a a dev $(VF) $(VF_IP_ADDRESS)
> ip l s dev $(VF) up
> ping $(VF_IP_ADDRESS)
ping is working fine here
> ip link set eth5 vf 0 vlan 100
> ip link set eth5 vf 0 vlan 0
> ping $(VF_IP_ADDRESS)
ping isn't working

The ice_vsi_add_vlan() function is used to add a VLAN filter for the target
VSI. This function prepares a filter in the switch table for the given VSI.
If it succeeds, the vsi->num_vlan counter is incremented.
It is not considered an error to add a VLAN which already exists in the
switch table, so the function explicitly checks and ignores -EEXIST. The
vsi->num_vlan counter is still incremented.
This seems incorrect, as it means we can double-count in the case where the
same VLAN is added twice by the caller. The actual table will have one less
filter than the count.
The ice_vsi_del_vlan() function similarly checks and handles the -ENOENT
condition for when deleting a filter that doesn't exist. This flow only
decrements the vsi->num_vlan if it actually deleted a filter.
The vsi->num_vlan counter is used only in a few places, primarily related
to tracking the number of non-zero VLANs. If the vsi->num_vlans gets out of
sync, then ice_vsi_num_non_zero_vlans() will incorrectly report more VLANs
than are present, and ice_vsi_has_non_zero_vlans() could return true
potentially in cases where there are only VLAN 0 filters left.
Fix this by only incrementing the vsi->num_vlan in the case where we
actually added an entry, and not in the case where the entry already
existed.

While converting to FIELD_PREP() and FIELD_GET(), it was noticed that
some of the RSS defines had *included* the shift in their definitions.
This is completely outside of normal, such that a developer could easily
make a mistake and shift at the usage site (like when using
FIELD_PREP()).
Rename the defines and set them to the "pre-shifted values" so they
match the template the driver normally uses for masks and the member
bits of the mask, which also allows the driver to use FIELD_PREP
correctly with these values. Use GENMASK() for this changed MASK value.
Do the same for the VLAN EMODE defines as well.

Refactor ice driver to use FIELD_PREP(), which reduces lines of code
and adds clarity of intent.
This code was generated by the following coccinelle/spatch script and
then manually repaired.
Several places I changed to OR into a single variable with |= instead of
using a multi-line statement with trailing OR operators, as it
(subjectively) makes the code clearer.
A local variable vmvf_and_timeout was created and used to avoid multiple
logical ORs being __le16 converted, which shortened some lines and makes
the code cleaner.
Also clean up a couple of places where conversions were made to have the
code read more clearly/consistently.

Port VLAN in this case means push and pop VLAN action on specific vid.
There are a few limitation in hardware:
- push and pop can't be used separately
- if port VLAN is used there can't be any trunk VLANs, because pop
action is done on all traffic received by VSI in port VLAN mode
- port VLAN mode on uplink port isn't supported
Reflect these limitations in code using dev_info to inform the user
about unsupported configuration.
In bridge mode there is a need to configure port vlan without resetting
VFs. To do that implement ice_port_vlan_on/off() functions. They are
only configuring correct vlan_ops to allow setting port vlan.
We also need to clear port vlan without resetting the VF which is not
supported right now. Change it by implementing clear_port_vlan ops.
As previous VLAN configuration isn't always the same, store current
config while creating port vlan and restore it in clear function.
Configuration steps:
- configure switchdev with bridge
- #bridge vlan add dev eth0 vid 120 pvid untagged
- #bridge vlan add dev eth1 vid 120 pvid untagged
- ping from VF0 to VF1

In order to support configuring the device in Double VLAN Mode (DVM),
the DDP and FW have to support DVM. If both support DVM, the PF that
downloads the package needs to update the default recipes, set the
VLAN mode, and update boost TCAM entries.
To support updating the default recipes in DVM, add support for
updating an existing switch recipe's lkup_idx and mask. This is done
by first calling the get recipe AQ (0x0292) with the desired recipe
ID. Then, if that is successful update one of the lookup indices
(lkup_idx) and its associated mask if the mask is valid otherwise
the already existing mask will be used.
The VLAN mode of the device has to be configured while the global
configuration lock is held while downloading the DDP, specifically after
the DDP has been downloaded. If supported, the device will default to
DVM.

Add a new outer_vlan_ops member to the ice_vsi structure as outer VLAN
ops are only available when the device is in Double VLAN Mode (DVM).
Depending on the VSI type, the requirements for what operations to
use/allow differ.
By default all VSI's have unsupported inner and outer VSI VLAN ops. This
implementation was chosen to prevent unexpected crashes due to null
pointer dereferences. Instead, if a VSI calls an unsupported op, it will
just return -EOPNOTSUPP.
Add implementations to support modifying outer VLAN fields for VSI
context. This includes the ability to modify VLAN stripping, insertion,
and the port VLAN based on the outer VLAN handling fields of the VSI
context.
These functions should only ever be used if DVM is enabled because that
means the firmware supports the outer VLAN fields in the VSI context. If
the device is in DVM, then always use the outer_vlan_ops, else use the
vlan_ops since the device is in Single VLAN Mode (SVM).
Also, move adding the untagged VLAN 0 filter from ice_vsi_setup() to
ice_vsi_vlan_setup() as the latter function is specific to the PF and
all other VSI types that need an untagged VLAN 0 filter already do this
in their specific flows. Without this change, Flow Director is failing
to initialize because it does not implement any VSI VLAN ops.

Current operations act on inner VLAN fields. To support double VLAN, outer
VLAN operations and functions will be implemented. Add the "inner" naming
to existing VLAN operations to distinguish them from the upcoming outer
values and functions. Some spacing adjustments are made to align
values.
Note that the inner is not talking about a tunneled VLAN, but the second
VLAN in the packet. For SVM the driver uses inner or single VLAN
filtering and offloads and in Double VLAN Mode the driver uses the
inner filtering and offloads for SR-IOV VFs in port VLANs in order to
support offloading the guest VLAN while a port VLAN is configured.

Currently the proto argument is unused. This is because the driver only
supports 802.1Q VLAN filtering. This policy is enforced via netdev
features that the driver sets up when configuring the netdev, so the
proto argument won't ever be anything other than 802.1Q. However, this
will allow for future iterations of the driver to seemlessly support
802.1ad filtering. Begin using the proto argument and extend the related
structures to support its use.

Add a new struct for VLAN related information. Currently this holds
VLAN ID and priority values, but will be expanded to hold TPID value.
This reduces the changes necessary if any other values are added in
future. Remove the action argument from these calls as it's always
ICE_FWD_VSI.

Incoming changes to support 802.1Q and/or 802.1ad VLAN filtering and
offloads require more flexibility when configuring VLANs. The VSI VLAN
interface will allow flexibility for configuring VLANs for all VSI
types. Add new files to separate the VSI VLAN ops and move functions to
make the code more organized.
