15ce76460a net/ixgbe: fix unexpected VLAN Rx in promisc mode on VF
When the promiscuous mode is enabled on a VF, the IXGBE_VMOLR_VPE
bit (VLAN Promiscuous Enable) is set. This means that the VF will
receive packets whose VLAN is not the same as the VLAN of the VF.

For instance, in this situation:

┌────────┐    ┌────────┐    ┌────────┐
│        │    │        │    │        │
│        │    │        │    │        │
│     VF0├────┤VF1  VF2├────┤VF3     │
│        │    │        │    │        │
└────────┘    └────────┘    └────────┘
   VM1           VM2           VM3

vf 0:  vlan 1000
vf 1:  vlan 1000
vf 2:  vlan 1001
vf 3:  vlan 1001

If we tcpdump on VF3, we see all the packets, even those transmitted
on vlan 1000.

This behavior prevents to bridge VF1 and VF2 in VM2, because it will
create a loop: packets transmitted on VF1 will be received by VF2 and
vice-versa, and bridged again through the software bridge.

This patch remove the activation of VLAN Promiscuous when a VF enables
the promiscuous mode. However, the IXGBE_VMOLR_UPE bit (Unicast
Promiscuous) is kept, so that a VF receives all packets that has the
same VLAN, whatever the destination MAC address.

8260929205 net/ixgbe: fix broadcast Rx on VF after promisc removal
After a VF requested to remove the promiscuous flag on an interface, the
broadcast packets are not received anymore. This breaks some protocols
like ARP.

In ixgbe_update_vf_xcast_mode(), we should keep the IXGBE_VMOLR_BAM
bit (Broadcast Accept) on promiscuous removal. This flag is already set
by default in ixgbe_vf_reset_event() on VF reset.

c2e3b84ec8 net/mlx5: fix null check in devargs parsing
The "mlx5_os_parse_eth_devargs()" function parses the ETH devargs into a
specific structure called "eth_da".
It gets structure called "devargs" as a member of EAL device containing
the relevant information.

When "devargs" structure is invalid, the function avoids parsing it.
However, when it valid but its field "args" is invalid, the function
tries to parse it and dereference to NULL pointer.

This patch adds check to avoid this NULL dereferencing.

bfa87e21bd net/mlx5: fix tunnel header with IPIP offload
For the flows with multiple tunnel layers and containing
tunnel decap and modify actions, for example:

... / vxlan / eth / ipv4 proto is 4 / end
actions raw_decap / modify_field / ...
(note: proto 4 means we have the IP-over-IP tunnel in VXLAN payload)

We have added the multiple tunnel layers validation rejecting
the flows like above mentioned one.

The hardware supports the above match combination till the inner
IP-over-IP header (not including the last one), both for IP-over-IPv4
and IP-over-IPv6, so we should not blindly reject. Also, for the modify
actions following the decap we should set the layer attributes correctly.

This patch reverts the below code changes to support the match, and
adjusts the layers update in case of decap with outer tunnel header.

9fa7c1cddb net/mlx5: create control flow rules with HWS
This patch adds the creation of control flow rules required to receive
default traffic (based on port configuration) with HWS.

Control flow rules are created on port start and destroyed on port stop.
Handling of destroying these rules was already implemented before that
patch.

Control flow rules are created if and only if flow isolation mode is
disabled and the creation process goes as follows:

- Port configuration is collected into a set of flags. Each flag
  corresponds to a certain Ethernet pattern type, defined by
  mlx5_flow_ctrl_rx_eth_pattern_type enumeration. There is a separate
  flag for VLAN filtering.

- For each possible Ethernet pattern type and:
  - For each possible RSS action configuration:
    - If configuration flags do not match this combination, it is
      omitted.
    - A template table is created using this combination of pattern
      and actions template (templates are fetched from hw_ctrl_rx
      struct stored in the port's private data).
    - Flow rules are created in this table.

483181f7b6 net/mlx5: support device control of representor matching
In some E-Switch use cases, applications want to receive all traffic
on a single port. Since currently, flow API does not provide a way to
match traffic forwarded to any port representor, this patch adds
support for controlling representor matching on ingress flow rules.

Representor matching is controlled through a new device argument
repr_matching_en.

- If representor matching is enabled (default setting),
  then each ingress pattern template has an implicit REPRESENTED_PORT
  item added. Flow rules based on this pattern template will match
  the vport associated with the port on which the rule is created.
- If representor matching is disabled, then there will be no implicit
  item added. As a result ingress flow rules will match traffic
  coming to any port, not only the port on which the flow rule is
  created.

Representor matching is enabled by default, to provide an expected
default behavior.

This patch enables egress flow rules on representors when E-Switch is
enabled in the following configurations:

- repr_matching_en=1 and dv_xmeta_en=4
- repr_matching_en=1 and dv_xmeta_en=0
- repr_matching_en=0 and dv_xmeta_en=0

When representor matching is enabled, the following logic is
implemented:

1. Creating an egress template table in group 0 for each port. These
   tables will hold default flow rules defined as follows:

      pattern SQ
      actions MODIFY_FIELD (set available bits in REG_C_0 to
                            vport_meta_tag)
              MODIFY_FIELD (copy REG_A to REG_C_1, only when
                            dv_xmeta_en == 4)
              JUMP (group 1)

2. Egress pattern templates created by an application have an implicit
   MLX5_RTE_FLOW_ITEM_TYPE_TAG item prepended to the pattern, which
   matches available bits of REG_C_0.

3. Egress flow rules created by an application have an implicit
   MLX5_RTE_FLOW_ITEM_TYPE_TAG item prepended to the pattern, which
   matches vport_meta_tag placed in available bits of REG_C_0.

4. Egress template tables created by an application, which are in
   group n, are placed in group n + 1.

5. Items and actions related to META are operating on REG_A when
   dv_xmeta_en == 0 or REG_C_1 when dv_xmeta_en == 4.

When representor matching is disabled and extended metadata is disabled,
no changes to the current logic are required.

773ca0e91b net/mlx5: support VLAN push/pop/modify with HWS
Add PMD implementation for HW steering VLAN push, pop, and modify flow
actions.

HWS VLAN push flow action is triggered by a sequence of mandatory
OF_PUSH_VLAN, OF_SET_VLAN_VID, and optional OF_SET_VLAN_PCP
flow action commands.

The commands must be arranged in the exact order:
OF_PUSH_VLAN / OF_SET_VLAN_VID [ / OF_SET_VLAN_PCP ].

In masked HWS VLAN push flow action template *ALL* the above flow
actions must be masked.

In non-masked HWS VLAN push flow action template *ALL* the above flow
actions must not be masked.

Example:

flow actions_template <port id> create \
actions_template_id <action id> \
template \
  of_push_vlan / \
  of_set_vlan_vid \
  [ / of_set_vlan_pcp  ] / end \
mask \
  of_push_vlan ethertype 0 / \
  of_set_vlan_vid vlan_vid 0 \
  [ / of_set_vlan_pcp vlan_pcp 0 ] / end\

flow actions_template <port id> create \
actions_template_id <action id> \
template \
  of_push_vlan ethertype <E>/ \
  of_set_vlan_vid vlan_vid <VID>\
  [ / of_set_vlan_pcp  <PCP>] / end \
mask \
  of_push_vlan ethertype <type != 0> / \
  of_set_vlan_vid vlan_vid <vid_mask != 0>\
  [ / of_set_vlan_pcp vlan_pcp <pcp_mask != 0> ] / end\

HWS VLAN pop flow action is triggered by OF_POP_VLAN
flow action command.
HWS VLAN pop action template is always non-masked.

Example:

flow actions_template <port id> create \
actions_template_id <action id> \
template of_pop_vlan / end mask of_pop_vlan / end

HWS VLAN VID modify flow action is triggered by a standalone
OF_SET_VLAN_VID flow action command.
HWS VLAN VID modify action template can be ether masked or non-masked.

Example:

flow actions_template <port id> create \
actions_template_id <action id> \
template of_set_vlan_vid / end mask of_set_vlan_vid vlan_vid 0 / end

flow actions_template <port id> create \

463170a7c9 net/mlx5: support connection tracking with HWS
This commit adds the support of connection tracking to HW steering as
SW steering did before.

The difference from SW steering implementation is that it takes
advantage of HW steering bulk action allocation support, in HW
steering only one single CT pool is needed.

An indexed pool is introduced to record allocated actions from bulk and
CT action state etc. Once one CT action is allocated from bulk, one
indexed object will also be allocated from the indexed pool, similar to
deallocating. That makes mlx5_aso_ct_action can also be managed by that
indexed pool, no need to be reserved from mlx5_aso_ct_pool. The single
CT pool is also saved to mlx5_aso_ct_action struct directly.

The ASO operation functions are shared with SW steering implementation.

This patch adapts mlx5 PMD to changes in mlx5dr API regarding the action

1. Actions template creation:

    - Flow actions types are translated to mlx5dr action types in order
      to create mlx5dr_action_template object.
    - An offset is assigned to each flow action. This offset is used to
      predetermine the action's location in the rule_acts array passed
      on the rule creation.

2. Template table creation:

    - Fixed actions are created and put in the rule_acts cache using
      predetermined offsets
    - mlx5dr matcher is parametrized by action templates bound to
      template table.
    - mlx5dr matcher is configured to optimize rule creation based on
      passed rule indices.

3. Flow rule creation:

    - mlx5dr rule is parametrized by the action template on which these
      rule's actions are based.
    - Rule index hint is provided to mlx5dr.

4d368e1da3 net/mlx5: support flow counter action for HWS
This commit adds HW steering counter action support.
The pool mechanism is the basic data structure for the HW steering
counter.

The HW steering's counter pool is based on the rte_ring of zero-copy
variation.

There are two global rte_rings:
1. free_list:
     Store the counters indexes, which are ready for use.
2. wait_reset_list:
     Store the counters indexes, which are just freed from the user and
     need to query the hardware counter to get the reset value before
     this counter can be reused again.

The counter pool also supports cache per HW steering's queues, which are
also based on the rte_ring of zero-copy variation.

The cache can be configured in size, preload, threshold, and fetch size,
they are all exposed via device args.

The main operations of the counter pool are as follows:

 - Get one counter from the pool:
   1. The user call _get_* API.
   2. If the cache is enabled, dequeue one counter index from the local
      cache:
      2. A: if the dequeued one from the local cache is still in reset
        status (counter's query_gen_when_free is equal to pool's query
        gen):
        I. Flush all counters in the local cache back to global
           wait_reset_list.
        II. Fetch _fetch_sz_ counters into the cache from the global
            free list.
        III. Fetch one counter from the cache.
   3. If the cache is empty, fetch _fetch_sz_ counters from the global
      free list into the cache and fetch one counter from the cache.
 - Free one counter into the pool:
   1. The user calls _put_* API.
   2. Put the counter into the local cache.
   3. If the local cache is full:

24865366e4 net/mlx5: support flow meter action for HWS
This commit adds meter action for HWS steering.

HW steering meter is based on ASO. The number of meters will
be used by flows should be specified in advance in the flow

ddb68e4733 net/mlx5: add extended metadata mode for HWS
The new mode 4 of devarg "dv_xmeta_en" is added for HWS only. In this
mode, the Rx / Tx metadata with 32b width copy between FDB and NIC is
supported.

The mark is only supported in NIC and there is no copy supported.

1939eb6f66 net/mlx5: support flow port action with HWS
This patch implements creating and caching of port action for use with
HW Steering FDB flows.

Actions are created on flow template API configuration and created
only on the port designated as the master. Attaching and detaching ports
in the same switching domain causes an update to the port actions cache
by, respectively, creating and destroying actions.

A new devarg fdb_def_rule_en is being added and it's used to control
the default dedicated E-Switch rules that are created by the PMD
implicitly or not, and PMD sets this value to 1 by default.

If set to 0, the default E-Switch rule will not be created and the user
can create the specific E-Switch rules on the root table if needed.

0f4aa72b99 net/mlx5: support flow modify field with HWS
This patch introduces support for modify_field rte_flow actions in HWS
mode that includes:
	- Ingress and egress domains,
	- SET and ADD operations,
	- usage of arbitrary bit offsets and widths for packet and metadata
	  fields.

This is implemented in two phases:
1. On flow table creation the hardware commands are generated, based
   on rte_flow action templates, and stored alongside action template.

2. On flow rule creation/queueing the hardware commands are updated with
   values provided by the user. Any masks over immediate values, provided
   in action templates, are applied to these values before enqueueing rules
   for creation.

7f6daa490d net/mlx5: add shared header reformat
As the rte_flow_async API defines the action mask with a field value
not being 0 means the action will be used as shared in all the flows
in the table.

The header reformat action with the action mask field not being 0 will
be created as constant shared action. For encapsulation header reformat
action, there are two kinds of encapsulation data, raw_encap_data
and rte_flow_item encap_data. Both of these two kinds of data can be
identified from the action mask conf as constant or not.

Examples:
1. VXLAN encap (encap_data: rte_flow_item)
	action conf (eth/ipv4/udp/vxlan_hdr)

	a. action mask conf (eth/ipv4/udp/vxlan_hdr)
	  - items are constant.
	b. action mask conf (NULL)
	  - items will change.

2. RAW encap (encap_data: raw)
	action conf (raw_data)

	a. action mask conf (not NULL)
	  - encap_data constant.
	b. action mask conf (NULL)
	  - encap_data will change.

b206c558f7 net/mlx5: fix IPv6 and TCP RSS hash fields
In the flow_dv_hashfields_set() function, while item_flags was 0,
the code went directly to the first if and the else case would
never have a chance to be checked. This caused the IPv6 and TCP hash
fields in the else case would never be set.

This commit adds the dedicated HW steering hash field set function
to generate the RSS hash fields.

Packets are steered from the table to the matcher and from there to
other objects.

The matcher allows efficient HW packet field matching and action
execution based on the configuration done to it.
