Currently, there is no flow aging check and age-out event callback
mechanism for mlx5 driver, this patch implements it. It's included:
- Splitting the current counter container to aged or no-aged container
since reducing memory consumption. Aged container will allocate extra
memory to save the aging parameter from user configuration.
- Aging check and age-out event callback mechanism based on current
counter. When a flow be checked aged-out, RTE_ETH_EVENT_FLOW_AGED
event will be triggered to applications.
- Implement the new API: rte_flow_get_aged_flows, applications can use
this API to get aged flows.

Currently, the counter pool needs 512 ext-counter memory for no batch
counters, it's allocated separately by once, behind the 512
basic-counter memory. This is not easy to get ext-counter pointer by
corresponding basic-counter pointer. This is also no easy for expanding
some other potential additional type of counter memory.
So, need allocate every one of ext-counter and basic-counter together,
as a single piece of memory. It's will be same for further additional
type of counter memory. In this case, one piece of memory contains all
type of memory for one counter, it's easy to get each type memory by
using offsetting.

The header modify actions number supported now has some limitation,
and it is decided by both driver and hardware. If the configuration
is different or the table to insert the flow is different, the result
might be different if the flow contains header modify actions.
Currently, the actual action number could only be calculated in the
later stage called translate, from user specified value to the driver
format. And the action numbers checking is missed in the flow
validation. So PMD will return incorrect result to indicate the
flow actions are valid by rte_flow_validate but then it will fail
when calling rte_flow_create.
Adding some simple checking in the validation will help to get rid
of this incorrect checking. Most of the actions will only consume 1
SW action field except the MAC address and IPv6 address. And from
SW POV, the maximal action fields for these will be consumed even if
only part of such field will be modified because that there is no
mask in the flow actions and the mask will always be all ONEs.
The metering or extra metadata supports will cost one more action.

When creating a flow, usually the creating routine is called in
serial. No parallel execution is supported right now. The same
function will be called only once for a single flow creation.
But there is a special case that the creating routine will be called
nested. If the xmeta feature is enabled and there is FLAG / MARK in
the actions list, some metadata reg copy flow needs to be created
before the original flow is applied to the hardware.
In the flow non-cached mode, resources only for flow creation will
not be saved anymore. The memory space is pre-allocated and reused
for each flow. A global index for each device is used to indicate
the memory address of the resources. If the function is called in a
nested mode, then the index will be reset and make everything get
corrupted.
To solve this, a nested index is introduced to save the position for
the original flow creation. Currently, only one level nested call
of the flow creating routine is supported.

On some virtual setups (particularly on ESXi) when we have SR-IOV and
E-Switch enabled there is the problem to receive VLAN traffic on VF
interfaces. The NIC driver in ESXi hypervisor does not setup E-Switch
vport setting correctly and VLAN traffic targeted to VF is dropped.
The patch provides the temporary workaround - if the rule
containing the VLAN pattern is being installed for VF the VLAN
network interface over VF is created, like the command does:
ip link add link vf.if name mlx5.wa.1.100 type vlan id 100
The PMD in DPDK maintains the database of created VLAN interfaces
for each existing VF and requested VLAN tags. When all of the RTE
Flows using the given VLAN tag are removed the created VLAN interface
with this VLAN tag is deleted.
The name of created VLAN interface follows the format:
evmlx.d1.d2, where d1 is VF interface ifindex, d2 - VLAN ifindex
Implementation limitations:
- mask in rules is ignored, rule must specify VLAN tags exactly,
no wildcards (which are implemented by the masks) are allowed
- virtual environment is detected via rte_hypervisor() call,
and the type of hypervisor is checked. Currently we engage
the workaround for ESXi and unrecognized hypervisors (which
always happen on platforms other than x86 - it means workaround
applied for the Flow over PCI VF). There are no confirmed data
the other hypervisors (HyperV, Qemu) need this workaround,
we are trying to reduce the list of configurations on those
workaround should be applied.

The DevX interface exposes a new feature to the PMD that can allocate a
batch of counters by one FW command. It can improve the flow
transaction rate (with count action).
Add a new counter pools mechanism to manage HW counters in the PMD.
So, for each flow with counter creation the PMD will try to find a free
counter in the PMD pools container and only if there is no a free
counter, it will allocate a new DevX batch counters.
Currently we cannot support batch counter for a group 0 flow, so
create a 2 container types, one which allocates counters one by
one and one which allocates X counters by the batch feature.
The allocated counters objects are never released back to the HW
assuming the flows maximum number will be close to the actual value of
the flows number.
Later, it can be updated, and dynamic release mechanism can be added.
The counters are contained in pools, each pool with 512 counters.
The pools are contained in counter containers according to the
allocation resolution type - single or batch.
The cache memory of the counters statistics is saved as raw data per
pool.
All the raw data memory is allocated for all the container in one
memory allocation and is managed by counter_stats_mem_mng structure
which registers all the raw memory to the HW.
Each pool points to one raw data structure.
The query operation is in pool resolution which updates all the pool
counter raw data by one operation.

- Currently, no device supports partial mask for protocol in IP header.
- As there could be multiple IP items, next_protocol variable in flow
validation has to be reset for inner layer. Otherwise, inner TCP/UDP
will see protocol number of outer IP header.
- Remove redundant protocol checking for MPLS, which is done in
mlx5_flow_validate_item_mpls().

Even though flow_drv_prepare() takes item_flags and action_flags to be
filled in, those are not used and will be overwritten by parsing of
flow_drv_translate(). There's no reason to keep the flags and fill it.
Appropriate notes are added to the documentation of flow_drv_prepare() and
flow_drv_translate().

1) Fix layer parsing
In translation of tunneled flows, dev_flow->layers must not be used to
check tunneled layer as it contains all the layers parsed from
flow_drv_prepare(). Checking tunneled layer is needed to set
IBV_FLOW_SPEC_INNER and it should be based on dynamic parsing. With
dev_flow->layers on a tunneled flow, items will always be interpreted as
inner as dev_flow->layer already has all the items.
2) Refactoring code
It is partly because flow_verbs_translate_item_*() sets layer flag. Same
code is repeating in multiple locations and that could be error-prone.
- Introduce VERBS_SPEC_INNER() to unify setting IBV_FLOW_SPEC_INNER.
- flow_verbs_translate_item_*() doesn't set parsing result -
MLX5_FLOW_LAYER_*.
- flow_verbs_translate_item_*() doesn't set priority or adjust hashfields
but does only item translation. Both have to be done outside.
- Make more consistent between Verbs and DV.
3) Remove flow_verbs_mark_update()
This code can never be reached as validation prohibits specifying mark and
flag actions together. No need to convert flag to mark.

Applications which add RSS rules must supply an RSS key and length.
If an application is only interested in default RSS operation it
should not care about the exact RSS key.
By setting the key to NULL - the PMD will use the default RSS key.
In addition if the application does not care about the RSS type it can
set it to 0 and the PMD will use the default type (ETH_RSS_IP).

The Flow counters created with Verbs are erroneously destroyed
in Flow remove function (flow_verbs_remove()). Counter Verbs
handles stored in the translated rule buffer become invalid.
If rule is reapplied with these invalid counter handles the
driver hangs.
The counter should be destroyed with Verbs in the Flow destroy
function. The Flow remove function should keep counters intact.

Both rte_flow and mlx5_flow redundantly have item flags. And it is not
properly set in the code. This causes wrong tunnel flag handling. A
rte_flow can have multiple expanded device flows if the flow has an RSS
action. Therefore, mlx5_flow should have the layers field.

This patch updates the functions performing the Verbs ibrary calls
in order to support different versions of the library.
The functions:
- flow_verbs_counter_new()
- flow_verbs_counter_release()
- flow_verbs_counter_query()
now have the several compilation branches, depending on the
counters support found in the system at compile time.
The flow_verbs_counter_create() function is introduced as
helper for flow_verbs_counter_new(), actually this helper
create the counters with Verbs.

The flow_verbs_query_count() is moved into the the group of counter
managing functions and renamed to flow_verbs_counter_query() in order
to be in unified fashion with others.
Also minor function modification is made to avoid unreachable code
warnings if there is no counter support at compile time.
