6dd571fd07 telemetry: introduce new functionality
This patch introduces a new telemetry connection socket and handling
functionality. Like the existing telemetry implementation (which is
unaffected by this change) it uses a unix socket, but unlike the
existing one it does not have a fixed list of commands - instead
libraries or applications can register telemetry commands and callbacks
to provide a full-extensible solution for all kinds of telemetry across
DPDK.

07c1b6925b telemetry: invert dependency on metrics library
Rather than having the telemetry library depend on the metrics
lib we invert the dependency so that metrics instead depends
on telemetry lib, and registers the needed functions with it
at init time. This prepares the way for a cleaner telemetry
architecture to be applied in later patches.

c5b7197f66 telemetry: move some functions to metrics library
This commit moves some of the telemetry library code to a new file in
the metrics library. No modifications are made to the moved code,
except what is needed to allow it to compile and run. The additional
code in metrics is built only when the Jansson library is  present.
Telemetry functions as normal, using the functions from the
metrics_telemetry file. This move will enable code be reused by the new
version of telemetry in a later commit, to support backward
compatibility with the existing telemetry usage.

points to the EAL header files so they utility macros etc. can be used

of target architecture to the top-level meson.build file so that the

0efc99bed3 net/mlx5: fix flow rules with Verbs
The flow_verbs_translate() function accumulates hash fields while
iterating through the flow items (SRC_IPV4, DST_IPV4, SRC_IPV6,
DST_IPV6, SRC_PORT_TCP, DST_PORT_TCP, SRC_PORT_UDP, DST_PORT_UDP).
Before this commit the dev_flow handle structure was reused in each new
flow_verbs_translate() call, however the dev_flow->hash_fields variable
was not reset before each call. As a result hash_fields from previous
calls remained present in the current flow which lead to invalid
combinations (e.g.  simultaneous IPv4 and IPv6 specs). This scenario
happens for example in the next flows sequence, when running in verbs
mode (dv_flow_en=0).

flow create 0 ingress group 0 pattern eth / ipv4 / end <rss actions>
flow create 0 ingress group 0 pattern eth / ipv6 / end <rss actions>

The fix is to reset dev_flow->hash_fields in flow_verbs_prepare().

3fc1d87c2a virtio: use one way barrier for split vring avail index
In case VIRTIO_F_ORDER_PLATFORM(36) is not negotiated, then the frontend
and backend are assumed to be implemented in software, that is they can
run on identical CPUs in an SMP configuration.
Thus a weak form of memory barriers like rte_smp_r/wmb, other than
rte_cio_r/wmb, is sufficient for this case(vq->hw->weak_barriers == 1)
and yields better performance.
For the above case, this patch helps yielding even better performance
by replacing the two-way barriers with C11 one-way barriers for avail
index in split ring.

68ca93e31c net/hns3: fix return value when clearing statistics
Since the return value of the '.stats_reset' and '.xstats_reset'
callback function is int, when failing to issue command to firmware to
execute clear statistics, the relevant callback function should return
non-zero value.

2de74dcfbd net/hns3: fix MSI-X interrupt during initialization
Currently, based on hns3 VF device error may occur during initialization.

The root cause as below:
When the following formula is executed during initialization, the
private variable named hw->tqps_num has not been obtained from PF driver
through mailbox, further causes failure when mapping interrupt and
queues.
  hw->num_msi = (num_msi > hw->tqps_num + 1) ? hw->tqps_num + 1 : num_msi;
We need to use hw->tqp_num after it is correctly assigned.

On the other hand, because the private variable named hw->num_msi, which
represents the number of MSI-x interrupt of hns3 PF/VF device, is used in
the '.get_reg' ops implementation function to dump all interrupt related
registers, it should be obtained from firmware directly and we'd better
not modify it in the driver.

99d673d5d3 net/hns3: fix VLAN PVID when configuring device
In current version, when upper level application calls the
rte_eth_dev_configure API function, if pvid config is not set of the
input parameter which struct type is rte_eth_conf, hns3 pmd driver also
sets the VLAN pvid related configuration to hardware, and this is not
reasonable. For example, As pvid is set to 100 by
rte_eth_dev_set_vlan_pvid, when pvid config is not set in rte_eth_conf,
rte_eth_dev_configure will tell driver to delete pvid 0, and that is
meaningless.

This patch fixes it to ensure that driver does not set VLAN pvid related
configuration to hardware when pvid config is not set in rte_eth_conf.

c4b7d6761d net/hns3: get Tx abnormal errors in xstats
When upper level application calls the rte_eth_tx_burst API function to
send multiple packets at a time with burst mode based on hns3 network
engine, there are some abnormal conditions that cause the driver to fail
to operate the hardware to send packets correctly.

This patch adds some statistic counts for the abnormal errors of Tx data
path to the extend device statistics. The upper level application can
get them by calling the rte_eth_xstats_get API function.

Note: When using burst mode to call the rte_eth_tx_burst API function to
send multiple packets at a time. When the first abnormal error is
detected, add one to the relevant error statistics item, and then exit
the loop of sending multiple packets of the function. That is to say,
even if there are multiple packets in which abnormal errors may be
detected in the burst, the relevant error statistics in the driver will
only be increased by one.

The detail description of the Tx abnormal errors statistic items as
below:
 - TX_OVER_LENGTH_PKT_CNT Total number of greater than
   HNS3_MAX_FRAME_LEN the driver supported.

 - TX_EXCEED_LIMITED_BD_PKT_CNT
     Total number of exceeding the hardware limited bd which process a
     packet needed bd numbers.

 - TX_EXCEED_LIMITED_BD_PKT_REASSEMBLE_FAIL_CNT
     Total number of exceeding the hardware limited bd fail which
     process a packet needed bd numbers and reassemble fail.

 - TX_UNSUPPORTED_TUNNEL_PKT_CNT
     Total number of unsupported tunnel packet. The unsupported tunnel
     type: vxlan_gpe, gtp, ipip and MPLSINUDP, MPLSINUDP is a packet
     with MPLS-in-UDP RFC 7510 header.

 - TX_QUEUE_FULL_CNT
     Total count which the available bd numbers in current bd queue is
     less than the bd numbers with the pkt process needed.

 - TX_SHORT_PKT_PAD_FAIL_CNT
     Total count which the packet length is less than minimum packet
     size HNS3_MIN_PKT_SIZE and fail to be appended with 0.
