Currently, there is a hard limitation on the PMD power management
support that only allows it to support a single queue per lcore. This is
not ideal as most DPDK use cases will poll multiple queues per core.
The PMD power management mechanism relies on ethdev Rx callbacks, so it
is very difficult to implement such support because callbacks are
effectively stateless and have no visibility into what the other ethdev
devices are doing. This places limitations on what we can do within the
framework of Rx callbacks, but the basics of this implementation are as
follows:
- Replace per-queue structures with per-lcore ones, so that any device
polled from the same lcore can share data
- Any queue that is going to be polled from a specific lcore has to be
added to the list of queues to poll, so that the callback is aware of
other queues being polled by the same lcore
- Both the empty poll counter and the actual power saving mechanism is
shared between all queues polled on a particular lcore, and is only
activated when all queues in the list were polled and were determined
to have no traffic.
- The limitation on UMWAIT-based polling is not removed because UMWAIT
is incapable of monitoring more than one address.
Also, while we're at it, update and improve the docs.

The vhost library currently configures Tx offloading (PKT_TX_*) on any
packet received from a guest virtio device which asks for some offloading.
This is problematic, as Tx offloading is something that the application
must ask for: the application needs to configure devices
to support every used offloads (ip, tcp checksumming, tso..), and the
various l2/l3/l4 lengths must be set following any processing that
happened in the application itself.
On the other hand, the received packets are not marked wrt current
packet l3/l4 checksumming info.
Copy virtio rx processing to fix those offload flags with some
differences:
- accept VIRTIO_NET_HDR_GSO_ECN and VIRTIO_NET_HDR_GSO_UDP,
- ignore anything but the VIRTIO_NET_HDR_F_NEEDS_CSUM flag (to comply with
the virtio spec),
Some applications might rely on the current behavior, so it is left
untouched by default.
A new RTE_VHOST_USER_NET_COMPLIANT_OL_FLAGS flag is added to enable the
new behavior.
The vhost example has been updated for the new behavior: TSO is applied to
any packet marked LRO.

Currently, the flow meter policy does not support multiple actions
per color; also the allowed action types per color are very limited.
In addition, the policy cannot be pre-defined.
Due to the growing in flow actions offload abilities there is a potential
for the user to use variety of actions per color differently.
This new meter policy API comes to allow this potential in the most ethdev
common way using rte_flow action definition.
A list of rte_flow actions will be provided by the user per color
in order to create a meter policy.
In addition, the API forces to pre-define the policy before
the meters creation in order to allow sharing of single policy
with multiple meters efficiently.
meter_policy_id is added into struct rte_mtr_params.
So that it can get the policy during the meters creation.
Allow coloring the packet using a new rte_flow_action_color
as could be done by the old policy API.
Add two common policy template as macros in the head file.
The next API function were added:
- rte_mtr_meter_policy_add
- rte_mtr_meter_policy_delete
- rte_mtr_meter_policy_update
- rte_mtr_meter_policy_validate
The next struct was changed:
- rte_mtr_params
- rte_mtr_capabilities
The next API was deleted:
- rte_mtr_policer_actions_update
To support this API the following app were changed:
app/test-flow-perf: clean meter policer
app/testpmd: clean meter policer
To support this API the following drivers were changed:
net/softnic: support meter policy API
1. Cleans meter rte_mtr_policer_action.
2. Supports policy API to get color action as policer action did.
The color action will be mapped into rte_table_action_policer.

Cleans and breaks part of the current meter management

This commit introduces the conntrack action and item.
Usually the HW offloading is stateless. For some stateful offloading
like a TCP connection, HW module will help provide the ability of a
full offloading w/o SW participation after the connection was
established.
The basic usage is that in the first flow rule the application should
add the conntrack action and jump to the next flow table. In the
following flow rule(s) of the next table, the application should use
the conntrack item to match on the result.
A TCP connection has two directions traffic. To set a conntrack
action context correctly, the information of packets from both
directions are required.
The conntrack action should be created on one ethdev port and supply
the peer ethdev port as a parameter to the action. After context
created, it could only be used between these two ethdev ports
(dual-port mode) or a single port. The application should modify the
action via the API "rte_action_handle_update" only when before using
it to create a flow rule with conntrack for the opposite direction.
This will help the driver to recognize the direction of the flow to
be created, especially in the single-port mode, in which case the
traffic from both directions will go through the same ethdev port
if the application works as an "forwarding engine" but not an end
point. There is no need to call the update interface if the
subsequent flow rules have nothing to be changed.
Query will be supported via "rte_action_handle_query" interface,
about the current packets information and connection status. The
fields query capabilities depends on the HW.
For the packets received during the conntrack setup, it is suggested
to re-inject the packets in order to make sure the conntrack module
works correctly without missing any packet. Only the valid packets
should pass the conntrack, packets with invalid TCP information,
like out of window, or with invalid header, like malformed, should
not pass.

Currently, DPDK application can offload the checksum check,
and report it in the mbuf.
However, as more and more applications are offloading some or all
logic and action to the HW, there is a need to check the packet
integrity so the right decision can be taken.
The application logic can be positive meaning if the packet is
valid jump / do actions, or negative if packet is not valid
jump to SW / do actions (like drop) and add default flow
(match all in low priority) that will direct the miss packet
to the miss path.
Since currently rte_flow works in positive way the assumption is
that the positive way will be the common way in this case also.
When thinking what is the best API to implement such feature,
we need to consider the following (in no specific order):
1. API breakage.
2. Simplicity.
3. Performance.
4. HW capabilities.
5. rte_flow limitation.
6. Flexibility.
First option: Add integrity flags to each of the items.
For example add checksum_ok to IPv4 item.
Pros:
1. No new rte_flow item.
2. Simple in the way that on each item the app can see
what checks are available.
Cons:
1. API breakage.
2. Increase number of flows, since app can't add global rule and must
have dedicated flow for each of the flow combinations, for example
matching on ICMP traffic or UDP/TCP traffic with IPv4 / IPv6 will
result in 5 flows.
Second option: dedicated item
Pros:
1. No API breakage, and there will be no for some time due to having
extra space. (by using bits)
2. Just one flow to support the ICMP or UDP/TCP traffic with IPv4 /
IPv6.
3. Simplicity application can just look at one place to see all possible
checks.
4. Allow future support for more tests.
Cons:
1. New item, that holds number of fields from different items.
For starter the following bits are suggested:
1. packet_ok - means that all HW checks depending on packet layer have
passed. This may mean that in some HW such flow should be split to
number of flows or fail.
2. l2_ok - all check for layer 2 have passed.
3. l3_ok - all check for layer 3 have passed. If packet doesn't have
L3 layer this check should fail.
4. l4_ok - all check for layer 4 have passed. If packet doesn't
have L4 layer this check should fail.
5. l2_crc_ok - the layer 2 CRC is O.K.
6. ipv4_csum_ok - IPv4 checksum is O.K. It is possible that the
IPv4 checksum will be O.K. but the l3_ok will be 0. It is not
possible that checksum will be 0 and the l3_ok will be 1.
7. l4_csum_ok - layer 4 checksum is O.K.
8. l3_len_OK - check that the reported layer 3 length is smaller than the
frame length.
Example of usage:
1. Check packets from all possible layers for integrity.
flow create integrity spec packet_ok = 1 mask packet_ok = 1 .....
2. Check only packet with layer 4 (UDP / TCP)
flow create integrity spec l3_ok = 1, l4_ok = 1 mask l3_ok = 1
l4_ok = 1

Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action should be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.
The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.
There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
within a flow rule. Such action is tied to its flow rule and
cannot be reused.
2. the indirect action, in the past, named shared_action. It is
created from a direct actioni, like count or rss, and then used
in the flow rules with an object handle. The PMD will take care
of the retrieve from indirect action to the direct action
when it is referenced.
The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.
The old name "shared" is improper in a sense and should be replaced.
Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*", the testpmd application code and command
line interfaces also need to be updated to do the adaption.
The testpmd application user guide is also updated. All the "shared
action" related parts are replaced with "indirect action" to have a
correct explanation.
The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
counter, the only "update" supported should be the reset. So
passing a rte_flow_action struct pointer is meaningless and
there is even no such corresponding action struct. What's more,
if more than one operations should be supported, for some other
action, such pointer parameter may not meet the need.
2. Some action may need conditional or partial update, the current
parameter will not provide the ability to indicate which part(s)
to update.
For different types of indirect action objects, the pointer could
either be the same of rte_flow_action* struct - in order not to
break the current driver implementation, or some wrapper
structures with bits as masks to indicate which part to be
updated, depending on real needs of the corresponding direct
action. For different direct actions, the structures of indirect
action objects updating will be different.
All the underlayer PMD callbacks will be moved to these new APIs.
The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.
Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*" and the "update" interface's 3rd input
parameter is changed to generic pointer, the mlx5 PMD that uses these
APIs needs to do the adaption to the new APIs as well.

Therefore, we can just remove the library prefix and use the library's

In case an event from a previous stage is required to be forwarded
to a crypto adapter and PMD supports internal event port in crypto
adapter, exposed via capability
RTE_EVENT_CRYPTO_ADAPTER_CAP_INTERNAL_PORT_OP_FWD, we do not have
a way to check in the API rte_event_enqueue_burst(), whether it is
for crypto adapter or for eth tx adapter.
Hence we need a new API similar to rte_event_eth_tx_adapter_enqueue(),
which can send to a crypto adapter.
Note that RTE_EVENT_TYPE_* cannot be used to make that decision,
as it is meant for event source and not event destination.
And event port designated for crypto adapter is designed to be used
for OP_NEW mode.
Hence, in order to support an event PMD which has an internal event port
in crypto adapter (RTE_EVENT_CRYPTO_ADAPTER_OP_FORWARD mode), exposed
via capability RTE_EVENT_CRYPTO_ADAPTER_CAP_INTERNAL_PORT_OP_FWD,
application should use rte_event_crypto_adapter_enqueue() API to enqueue

When internal port is not available(RTE_EVENT_CRYPTO_ADAPTER_OP_NEW mode),
application can use API rte_event_enqueue_burst() as it was doing earlier,
i.e. retrieve event port used by crypto adapter and bind its event queues

Add a simple on/off switch that will enable saving power when no
packets are arriving. It is based on counting the number of empty
polls and, when the number reaches a certain threshold, entering an
architecture-defined optimized power state that will either wait
until a TSC timestamp expires, or when packets arrive.
This API mandates a core-to-single-queue mapping (that is, multiple
queued per device are supported, but they have to be polled on different
cores).
This design is using PMD RX callbacks.
1. UMWAIT/UMONITOR:
When a certain threshold of empty polls is reached, the core will go
into a power optimized sleep while waiting on an address of next RX
descriptor to be written to.
2. TPAUSE/Pause instruction
This method uses the pause (or TPAUSE, if available) instruction to
avoid busy polling.
3. Frequency scaling
Reuse existing DPDK power library to scale up/down core frequency
depending on traffic volume.

Implement the generic modify flow API to allow manipulations on
an arbitrary header field (as well as mark, metadata or tag) using
data from another field or a user-specified value.
This generic modify mechanism removes the necessity to implement
a separate RTE Flow action every time we need to modify a new packet
field in the future.
Supported operation are:
- set: copy data from source to destination.
- add: integer addition, stores the result in destination.
- sub: integer subtraction, stores the result in destination.
The field ID is used to specify the desired source/destination packet
field in order to simplify the API for various encapsulation models.
Specifying the packet field ID with the needed encapsulation level
is able to quickly get a packet field for any inner packet header.
Alternatively, the special ID (ITEM_START) can be used to point to
the very beginning of a packet. This ID in conjunction with the
offset parameter provides great flexibility to copy/modify any part of
a packet as needed.
The number of bits to use from a source as well as the offset can be
be specified to allow a partial copy or dividing a big packet field
into multiple small fields (e.g. copying 128 bits of IPv6 to 4 tags).
An immediate value (or a pointer to it) can be specified instead of the
level and the offset for the special FIELD_VALUE ID (or FIELD_POINTER).
Can be used as a source only.

Async enqueue offloads large copies to DMA devices, and small copies
are still performed by the CPU. However, it requires users to get
enqueue completed packets by rte_vhost_poll_enqueue_completed(), even
if they are completed by the CPU when rte_vhost_submit_enqueue_burst()
returns. This design incurs extra overheads of tracking completed
pktmbufs and function calls, thus degrading performance on small packets.
This patch enhances async enqueue for small packets by enabling
rte_vhost_submit_enqueue_burst() to return completed packets.

There is a discrepancy between ethdev API and flow rules guide
regarding flow rules maintenance after port stop.
librte_ethdev.h declares that flow rules will not be stored in PMD
after port stop:
>>>>> Quote start
Please note that some configuration is not stored between calls to
rte_eth_dev_stop()/rte_eth_dev_start(). The following configuration
will be retained:
- MTU
- flow control settings
- receive mode configuration (promiscuous mode, all-multicast mode,
hardware checksum mode, RSS/VMDQ settings etc.)
- VLAN filtering configuration
- default MAC address
- MAC addresses supplied to MAC address array
- flow director filtering mode (but not filtering rules)
- NIC queue statistics mappings
<<<< Quote end
PMD cannot always correctly restore flow rules after port stop / port
start because application may alter port configuration after port stop
without PMD knowledge about undergoing changes. Consider the
following scenario:
application configures 2 queues 0 and 1 and creates a flow rule with
'queue index 1' action. After that application stops the port and
removes queue 1.
Although PMD can implement flow rule shadow copy to be used for
restore after port start, attempt to restore flow rule from shadow
will fail in example above and PMD could not notify application about
that failure. As the result, flow rules map in HW will differ from
what application expects. In addition, flow rules shadow copy used
for port start restore consumes considerable amount of system memory,
especially in systems with millions of flow rules.

rte_gso_segment decreased refcnt of pkt by one, but
it is wrong if pkt is external mbuf, pkt won't be
freed because of incorrect refcnt, the result is
application can't allocate mbuf from mempool because
mbufs in mempool are run out of.
One correct way is application should call
rte_pktmbuf_free after calling rte_gso_segment to free
pkt explicitly. rte_gso_segment must not handle it, this
should be responsibility of application.
This commit changed rte_gso_segment in functional behavior
and return value, so the application must take appropriate
actions according to return values, "ret < 0" means it
should free and drop 'pkt', "ret == 0" means 'pkt' isn't
GSOed but 'pkt' can be transmitted as a normal packet,
"ret > 0" means 'pkt' has been GSOed into two or multiple
segments, it should use "pkts_out" to transmit these
segments. The application must free 'pkt' after call
rte_gso_segment when return value isn't equal to 0.
