ethdev: fix RSS flow expansion in case of mismatch
Function rte_flow_expand_rss() is used to expand a flow rule with
partial pattern into several rules, to ensure all relevant packets
are matched.
It uses utility function rte_flow_expand_rss_item_complete(), to check
if the last valid item in the flow rule pattern needs to be completed.
For example the pattern "eth / ipv4 proto is 17 / end" will be completed
with a "udp" item.
This function returns "void" item in two cases:
1) The last item has empty spec, for example "eth / ipv4 / end".
2) The last itme has spec that can't be expanded for RSS.
For example the pattern "eth / ipv4 proto is 47 / end" ends with IPv4
item that has next protocol GRE.
In both cases the flow rule may be expanded, but in the second case such
expansion may create rules with invalid pattern.
For example "eth / ipv4 proto is 47 / udp / end".
In such a case the flow rule should not be expanded.
This patch updates function rte_flow_expand_rss_item_complete().
Return value RTE_FLOW_ITEM_TYPE_END is used to indicate the flow rule
should not be expanded.
In such a case, rte_flow_expand_rss() will return with the original flow
rule only, without any expansion.

net/hns3: fix error type when validating RSS flow action
Because the macro named RTE_FLOW_ERROR_TYPE_ACTION_CONF indicates a
action configuration and the macro named RTE_FLOW_ERROR_TYPE_ACTION
indicates a specific action, the driver needs to return
RTE_FLOW_ERROR_ACTION_CONF type and notify the user when a RSS
configuration is invalid with actions list in the internal function
named hns3_parse_rss_filter called by the '.validate' ops implementation
function named hns3_flow_validate.
Besides, this patch removes some unnecessary judgment lines in

net/hns3: maximize queue number
The maximum number of queues for hns3 PF and VF driver is 64 based on
hns3 network engine with revision_id equals 0x21. Based on hns3 network
engine with revision_id equals 0x30, the hns3 PF PMD driver can support
up to 1280 queues, and hns3 VF PMD driver can support up to 128 queues.
The following points need to be modified to support maximizing queue
number and maintain better compatibility:
1) Maximizing the number of queues for hns3 PF and VF PMD driver In
current version, VF is not supported when PF is driven by hns3 PMD
driver. If maximum queue numbers allocated to PF PMD driver is less
than total tqps_num allocated to this port, all remaining number of
queues are mapped to VF function, which is unreasonable. So we fix
that all remaining number of queues are mapped to PF function.
Using RTE_LIBRTE_HNS3_MAX_TQP_NUM_PER_PF which comes from
configuration file to limit the queue number allocated to PF device
based on hns3 network engine with revision_id greater than 0x30. And
PF device still keep the maximum 64 queues based on hns3 network
engine with revision_id equals 0x21.
Remove restriction of the macro HNS3_MAX_TQP_NUM_PER_FUNC on the
maximum number of queues in hns3 VF PMD driver and use the value
allocated by hns3 PF kernel netdev driver.
2) According to the queue number allocated to PF device, a variable
array for Rx and Tx queue is dynamically allocated to record the
statistics of Rx and Tx queues during the .dev_init ops
implementation function.
3) Add an extended field in hns3_pf_res_cmd to support the case that
numbers of queue are greater than 1024.
4) Use new base address of Rx or Tx queue if QUEUE_ID of Rx or Tx queue
is greater than 1024.
5) Remove queue id mask and use all bits of actual queue_id as the
queue_id to configure hardware.
6) Currently, 0~9 bits of qset_id in hns3_nq_to_qs_link_cmd used to
record actual qset id and 10 bit as VLD bit are configured to
hardware. So we also need to use 11~15 bits when actual qset_id is
greater than 1024.
7) The number of queue sets based on different network engine are
different. We use it to calculate group number and configure to
hardware in the backpressure configuration.
8) Adding check operations for number of Rx and Tx queue user configured
when mapping queue to tc Rx queue numbers under a single TC must be
less than rss_size_max supported by a single TC. Rx and Tx queue
numbers are allocated to every TC by average. So Rx and Tx queue
numbers must be an integer multiple of 2, or redundant queues are not
available.
9) We can specify which packets enter the queue with a specific queue
number, when creating flow table rules by rte_flow API. Currently,
driver uses 0~9 bits to record the queue_id. So it is necessary to
extend one bit field to record queue_id and configure to hardware, if
the queue_id is greater than 1024.

net/hns3: expand number of queues for one TC up to 512
The maximum number of queues for one TC hns3 PF PMD driver supported is
64 based on hns3 network engine with revision_id equals 0x21, while it
is expanded up to 512 on hns3 network engine with revision_id equals
0x30.
So the following points need to be modified to maintain better
compatibility.
1) Using a extended rss_size_max field as the maximum queue number of
one TC PF driver supported.
2) The data type of the RSS redirection table needs to be changed from
uint8_t to uint16_t.
3) rss_tc_mode modification
The bitwidth of tc_offset, meaning the rx queue index, has to expand
from 10 bit to 11 bits. The tc_size, meaning the exponent with base 2
of queues supported on TC, needs to expand from 3 bits to 4 bits.
4) RSS indirection table modification
Currently, a field with 7 bits width is used to record the queue
index for RSS indirection table. It means that PF needs to expand the
queue index field to 9 bits. As the RSS indirection table config
command reserved 4 bytes to configure the RSS queue index, a extern
field can be added. So an entries of RSS indirection table queue
index has two fields to set: rss_result_l and rss_result_h, while
rss_result_l records the lower 8 bits and rss_result_h records the
higher 1 bit.
In addition, 2~4 modifications is also compatible with hns3 VF PMD
driver.

timer: add limitation note for sync stop and reset
If a timer's callback function calls rte_timer_reset_sync() or
rte_timer_stop_sync() on another timer that is in the RUNNING state and
owned by the current lcore, the *_sync() calls will loop indefinitely.
Relatedly, if a timer's callback function calls *_sync() on another
timer that is in the RUNNING state and is owned by a different lcore,
but a timer callback function runs on that different lcore and calls
*_sync() on a timer that is in the RUNNING state and owned by the
current lcore, the two lcores will loop indefinitely.
Add a note in the rte_timer_stop_sync and rte_timer_reset_sync
documentation that indicates that these APIs should not be used inside
timer callback functions in order to avoid the hangs described above,
and suggests an alternative.

power: fix current frequency index
During power initialization the pstate cpufreq api is
not setting the initial curr_idx of pstate_power_info
to corresponding current frequency index.
Without this the idx is always 0, which is causing the
below check to pass and returns without setting the initial
min/max frequency to system max frequency and this leads to
incorrect frequency settings when power_pstate_cpufreq_set_freq()
is called in the apps.
set_freq_internal(struct pstate_power_info *pi, uint32_t idx)
{
...
/* Check if it is the same as current */
if (idx == pi->curr_idx)
return 0;
...
}
scenario 1:
If system has starting scaling min/max: 1000/1000, and want to
set this to 2200/2200, the max frequency gets updated but not min.
scenario 2:
If system has starting scaling min/max: 2200/1000, and want to set
to 2200/2200, the max, min frequency was not updated. Since no change
in max that should be ok, but min was also ignored, which will be fixed
now with the new changes.

raw/skeleton: allow closing already closed device
This patch return OK code (0) from skeleton_rawdev_close function
if firmware is in SKELETON_FW_READY state. Formerly it returned
-EINVAL error code.
Returning an error here is troublesome as it disallows proper release
of the rawdev. The rte_rawdev_pmd_release function from librte_rawdev
library calls drivers' rawdev_close handler and continues execution
only in case of errorless call.
(see lib/librte_rawdev/rte_rawdev.c:540)
The SKELETON_FW_READY state is reached after creation, reset, unload
or close of the device. The device should be ok to be released in
such situations.
To reproduce issue fixed by this patch, call rawdev_autotest
from dpdk-test app for few times. As the device is not properly
released, the next calls will fail.

test/telemetry: add unit tests for data to JSON
This patch adds tests for verifying telemetry data structures are
converted to JSON as expected. Both flat and recursive data structures
are tested, for all possible value types.
The app connects to the telemetry socket as a client, and registers one
command with a corresponding callback function. Each time the callback
function is called, it copies a global data variable to the data pointer
passed in by telemetry.
When a test case is run, the test case function builds up the global
data variable with the relevant data types, and the expected json string
output which should be generated from that. The 'test_output()' function
is used to trigger the callback and ensure the actual output matches
that expected.

telemetry: support array values in data object
Arrays of type uint64_t/int/string can now be included within an array
or dict. One level of embedded containers is supported. This is
necessary to allow for instances such as the ethdev queue stats to be
reported as a list of uint64_t values, rather than having multiple dict
entries with one uint64_t value for each queue stat.
The memory management APIs provided by telemetry simplify the memory
allocation/free aspect of the embedded container. The rte_tel_data_alloc
function is called in the library/app callback to return a pointer to a
container that has been allocated memory. When adding this container
to an array/dict, a parameter is passed to indicate if the memory
should be freed by telemetry after use. This will allow reuse of the
allocated memory if the library/app wishes to do so.
