The virtual channel is going to be extended to support FDIR and
RSS configure from AVF. New data structures and OP codes will be
added, the patch enable the FDIR part.

To support above advanced AVF feature, we need to figure out
what kind of data structure should be passed from VF to PF to describe
an FDIR rule or RSS config rule. The common part of the requirement is
we need a data structure to represent the input set selection of a rule's
hash key.

An input set selection is a group of fields be selected from one or more
network protocol layers that could be identified as a specific flow.
For example, select dst IP address from an IPv4 header combined with
dst port from the TCP header as the input set for an IPv4/TCP flow.

The patch adds a new data structure virtchnl_proto_hdrs to abstract
a network protocol headers group which is composed of layers of network
protocol header(virtchnl_proto_hdr).

A protocol header contains a 32 bits mask (field_selector) to describe
which fields are selected as input sets, as well as a header type
(enum virtchnl_proto_hdr_type). Each bit is mapped to a field in
enum virtchnl_proto_hdr_field guided by its header type.

+------------+-----------+------------------------------+
|            | Proto Hdr | Header Type A                |
|            |           +------------------------------+
|            |           | BIT 31 | ... | BIT 1 | BIT 0 |
|            |-----------+------------------------------+
|Proto Hdrs  | Proto Hdr | Header Type B                |
|            |           +------------------------------+
|            |           | BIT 31 | ... | BIT 1 | BIT 0 |
|            |-----------+------------------------------+
|            | Proto Hdr | Header Type C                |
|            |           +------------------------------+
|            |           | BIT 31 | ... | BIT 1 | BIT 0 |
|            |-----------+------------------------------+
|            |    ....                                  |
+-------------------------------------------------------+

All fields in enum virtchnl_proto_hdr_fields are grouped with header type
and the value of the first field of a header type is always 32 aligned.

enum proto_hdr_type {
        header_type_A = 0;
        header_type_B = 1;
        ....
}

enum proto_hdr_field {
        /* header type A */
        header_A_field_0 = 0,
        header_A_field_1 = 1,
        header_A_field_2 = 2,
        header_A_field_3 = 3,

        /* header type B */
        header_B_field_0 = 32, // = header_type_B << 5
        header_B_field_0 = 33,
        header_B_field_0 = 34
        header_B_field_0 = 35,
        ....
};

So we have:
proto_hdr_type = proto_hdr_field / 32
bit offset = proto_hdr_field % 32

To simply the protocol header's operations, couple help macros are added.
For example, to select src IP and dst port as input set for an IPv4/UDP
flow.

we have:
struct virtchnl_proto_hdr hdr[2];

VIRTCHNL_SET_PROTO_HDR_TYPE(&hdr[0], IPV4)
VIRTCHNL_ADD_PROTO_HDR_FIELD(&hdr[0], IPV4, SRC)

VIRTCHNL_SET_PROTO_HDR_TYPE(&hdr[1], UDP)
VIRTCHNL_ADD_PROTO_HDR_FIELD(&hdr[1], UDP, DST)

The byte array is used to store the protocol header of a training package.
The byte array must be network order.

The patch added virtual channel support for iAVF FDIR add/validate/delete
filter. iAVF FDIR is Flow Director for Intel Adaptive Virtual Function
which can direct Ethernet packets to the queues of the Network Interface
Card. Add/delete command is adding or deleting one rule for each virtual
channel message, while validate command is just verifying if this rule
is valid without any other operations.

To add or delete one rule, driver needs to config TCAM and Profile,
build training packets which contains the input set value, and send
the training packets through FDIR Tx queue. In addition, driver needs to
manage the software context to avoid adding duplicated rules, deleting
non-existent rule, input set conflicts and other invalid cases.

NOTE:
Supported pattern/actions and their parse functions are not be included in
this patch, they will be added in a separate one.

We are going to enable FDIR configure for AVF through virtual channel.
The first step is to add helper functions to support control VSI setup.
A control VSI will be allocated for a VF when AVF creates its
first FDIR rule through ice_vf_ctrl_vsi_setup().
The patch will also allocate FDIR rule space for VF's control VSI.
If a VF asks for flow director rules, then those should come entirely
from the best effort pool and not from the guaranteed pool. The patch
allow a VF VSI to have only space in the best effort rules.

This reverts commit e9bf9694.

The topic of the reverted patch is the support for switches with global
VLAN filtering, added by commit 061f6a50 ("net: dsa: Add
ndo_vlan_rx_{add, kill}_vid implementation"). Be there a switch with 4
ports swp0 -> swp3, and the following setup:

ip link add br0 type bridge vlan_filtering 1
ip link set swp0 master br0
ip link set swp1 master br0

What would happen with VLAN-tagged traffic received on standalone ports
swp2 and swp3? Well, it would get dropped, were it not for the
.ndo_vlan_rx_add_vid and .ndo_vlan_rx_kill_vid implementations (called
from vlan_vid_add and vlan_vid_del respectively). Basically, for DSA
switches where VLAN filtering is a global attribute, we enforce the
standalone ports to have 'rx-vlan-filter: off [fixed]' in their ethtool
features, which lets the user know that all VLAN-tagged packets that are
not explicitly added in the RX filtering list are dropped.

As for the sja1105 driver, at the time of the reverted patch, it was
operating in a pretty handicapped mode when it had ports under a bridge
with vlan_filtering=1. Specifically, it was unable to terminate traffic
through the CPU port (for further explanation see "Traffic support" in
Documentation/networking/dsa/sja1105.rst).

However, since then, the sja1105 driver has made considerable progress,
and that limitation is no longer as severe now. Specifically, since
commit 2cafa72e ("net: dsa: sja1105: add a new
best_effort_vlan_filtering devlink parameter"), the driver is able to
perform CPU termination even when some ports are under bridges with
vlan_filtering=1. Then, since commit 8841f6e6 ("net: dsa: sja1105:
make devlink property best_effort_vlan_filtering true by default"), this
even became the default operating mode.

So we can now take advantage of the logic in the DSA core.

net: ipa: more configuration data updates

This series starts with two patches that should have been included
in an earlier series.  With these in place, QSB settings are
programmed from information found in the data files rather than
being embedded in code.  Support is then added for reprenting
another QSB property (supported for IPA v4.0+).

The third patch updates the definition of the sequencer type used
for an endpoint.  Previously a set of 2-byte symbols with fairly
long names defined the sequencer type, but now those are broken into
1-byte halves whose names are a little more informative.

The fourth patch moves the sequencer type definition so it only
applies to TX endpoints (they aren't valid for RX endpoints).  And
the last makes some minor documentation updates.

We only program the sequencer type for TX endpoints.  So move the
definition of the sequencer type fields into the TX-specific portion
of the endpoint configuration data.  There's no need to maintain
this in the IPA structure; we can extract it from the configuration
data it points to in the one spot it's needed.

We previously specified the sequencer type for RX endpoints with
INVALID values.  These are no longer needed, so get rid of them.

An IPA endpoint has a sequencer that must be configured based on how
the endpoint is to be used.  Currently the IPA code programs the
sequencer type by splitting a value into four 4-bit nibbles.  Doing
that doesn't really add much value, and regardless, a better way of
splitting the sequencer type is into two halves--the lower byte
describing how normal packet processing is handled, and the next
byte describing information about processing replicas.

So split the sequencer type into two sub-parts:  the sequencer type
and the replication sequencer type.  Define the values supported for
the "main" sequencer type, and define the values supported for the
replication part separately.

In addition, the sequencer type names are quite verbose, encoding
what the type includes, but also what it *excludes*.  Rename the
sequencer types in a way that mainly describes the number of passes
that a packet takes through the IPA processing pipeline, and how
many of those passes end by supplying the processed packet to the
microprocessor.

The result expands the supported types beyond what is required for
now, but simplifies the way these are defined.

enetc_teardown_cbdr from all the places where enetc_free_si_resources
was called. In particular, now it is no longer called from the main
unbind function, just from the probe error path.

The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.
