cdfa0dc170 net/ice/base: fix uninitialized stack variables
Via code inspection, I found that some partially initialized
stack variables were being passed along to called functions,
which could eventually result in those uninitialized members
being used.  To fix this, make sure the local variables are
zeroed out before partially initializing them.  This should
prevent any unintended consequences from using stack memory that
might have junk in it.

In addition to the memsets, this patch also initializes one
member in one function, that needed to be initialized to non-zero.

e7f4213c30 net/hns3: fix return value of setting VLAN offload
Currently, the '.vlan_offload_set' ops implementation function named
hns3vf_vlan_offload_set always return 0 in hns3 VF PMD driver.

This patch fixes it with the following modification in the function
named hns3vf_vlan_offload_set.
1. Avoid setting hardware configuration and return -EIO during resetting.
2. Add the return value detection process for calling internal static

5e782bc257 net/hns3: fix configuring RSS hash when rules are flushed
Currently, when performing test case as follow:
1. Run testpmd application based on hns3 network engine with multiple
   receive queues(--rxq=N --txq=N, N>1).
2. Create the special RSS rules by "create flow ..." command in the
   command prompt of the testpmd application.
3. Flush the RSS rules created in step 2 by "flow flush ..." command.
4. Enable RSS by "port config all rss all" command.
In step 4, the command exeuctes successfully. This phenomenon is
inconsistent with the expectation. The API function named
rte_eth_dev_rss_hash_update called in the command should return error
and the command should fail.

This patch fixes it by adding a flag for disabling RSS in the driver.
When RSS rules is flushed, we set the the flag with true, and the
'.rss_hash_update' ops implementation function named
hns3_dev_rss_hash_update return -EINVAL.

920be799db net/hns3: fix RSS indirection table configuration
For the current hns3 PMD driver, there are some RSS related bugs at
the following scenes:
1. Start the application with the number of Rx queues equals 1(--rxq=1),
   modify the number of Rx queue to some number greater than 1 during
   normal operation. As a result, upper application can't receive packets
   from multiple rx queues.
2. Start testpmd application with the option disable-rss and the number
   of Rx queue is greater than 1(--disable-rss --rxq=N, N>1). As a result,
   upper application still can receive packets from multiple rx queues.

The root cause as below:
There are some error configuration in the RSS indirection table of hns3
network engine.

This patch fixes them with the following modification.
1. When RSS size is changed, we need to update RSS redirection table
   maintained by driver and configure them to hardware. Besides, during
   the entire reset process, we need to ensure that the RSS table
   information are not overwritten and configured directly to the hardware
   in the RESET_STAGE_RESTORE stage of the reset process.
2. When sarting testpmd application with the options disable-rss, it
   doesn't need to configure RSS redirection table to hardware.

25d257facd net/hns3: fix status after repeated resets
Currently, when performing the following test case:
1. Run testpmd application based on hns3 PF device.
2. Inject reset(global/IMP reset) repeatedly.
After the reset, the network port can't link up.

In the RESET_STAGE_DEV_INIT stage of the reset process, the driver will
reinitialize the hardware. If global/IMP reset occurs at this time
again, the operation of reinitialize the hardware will fail because that
firmware don't respond to the configuration commands issued by driver.
In current driver, when failed to reinitialize the hardware, rollback
operation is done, such as clearing the relevant configuration of the
command queue registers.

If firmware detects that the function's command queue register is not
configured correctly, it will not complete the reset related hardware
configuration for this function, resulting in that driver can't detect
that the hardware reset has been completed. And then the reset process
of the driver exit abnormally, the hardware can not work normally after
reset.

This patch fixes it by avoid clearing the command queue related
registers when failed to reinitialize the hardware in the
RESET_STAGE_DEV_INIT stage of the reset process.

the way the '.flush' ops is defined in the struct rte_flow_ops, if

invalid(filled with 0x44444444 in port_flow_flush function of the
testpmd application), it leads to segmentation fault when format the
message.

We fixes it by filling error parameter when failure in calling static

4f4ee5b79b net/hns3: fix default error code of command interface
Currently, the hns3 PMD driver can interact with firmware through
command to complete hardware configuration. The driver calls internal
interface function named hns3_cmd_send to issues command to the
firmware, and check the execution result of the command through desc_ret
returned by firmware to driver.

As the design of error code, when device is resetting hns3_cmd_send will
only return -EBUSY or -EIO. But we found that if desc_ret is in
[12,65535], for example the item doesn't exist when issuing the command
to query some table item, hns3_cmd_send also return -EIO. This
phenomenon will affect the processing logic for the return value.

The root cause as below:
When desc_ret is in [12,65535], in the static function named
hns3_cmd_convert_err_code called by hns3_cmd_send, matches the default
case and return -EIO. And then hns3_cmd_send return -EIO.

This patch fixes it with the following modification.
1. Change the return value of the default case in the static function
   named hns3_cmd_convert_err_code from -EIO to -EREMOTEIO.
2. Modify the comment add errcode description of the internal interface
   function named hns3_cmd_send.

af531efa4b net/hns3: fix packets offload features flags in Rx
Currently there is a certain probability of the unexpected ol_flag of
the Rx packets's rte_mbuf when receiving packets.

The root cause as below:
1. The member variable named ol_flag of the structure named rte_mbuf is
   not properly initialized to zero in the '.rx_pkt_burst' ops
   implementation function named hns3_recv_pkts.
2. When multi-segment rte_mbufs are needed for long packet in Rx
   operation, the driver should assign value to the ol_flag of the first
   segment, not to the ol_flag of the last segment.

This patch fixes it with the following modification in the
'.rx_pkt_burst' ops implementation function named hns3_recv_pkts.
1. Where the first write operation in the '.rx_pkt_burst' ops
   implementation function, assign PKT_RX_RSS_HASH to ol_flags directly
   using '=' operation instead of '|=' operation.
2. In the static function named hns3_rx_set_cksum_flag, the last
   rte_mbuf's ol_flags should be assigned when processing multi-segment.
   We fix it by passing first_seg variable to the function instead of
   rxm(the last segment's address).

Add the following memory-related tracepoints.

- rte_eal_trace_mem_zmalloc()
- rte_eal_trace_mem_malloc()
- rte_eal_trace_mem_realloc()
- rte_eal_trace_mem_free()

rte_malloc() and rte_free() has been used in the trace implementation,
in order to avoid tracing implementation specific events, added
an internal no trace version rte_malloc() and rte_free().

6c232fc44c trace: add generic tracepoints
This patch creates the following generic tracepoint for
generic tracing when there is no dedicated tracepoint is
available.

- rte_eal_trace_generic_void()
- rte_eal_trace_generic_u64()
- rte_eal_trace_generic_u32()
- rte_eal_trace_generic_u16()
- rte_eal_trace_generic_u8()
- rte_eal_trace_generic_i64()
- rte_eal_trace_generic_i32()
- rte_eal_trace_generic_i16()
- rte_eal_trace_generic_i8()
- rte_eal_trace_generic_int()
- rte_eal_trace_generic_long()
- rte_eal_trace_generic_float()
- rte_eal_trace_generic_double()
- rte_eal_trace_generic_ptr()
- rte_eal_trace_generic_str()

For example, if an application wishes to emit an int datatype,
it can call rte_eal_trace_generic_int(val) to emit the trace.

032a7e5499 trace: implement provider payload
The trace function payloads such as rte_trace_point_emit_* have
dual functions. The first to emit the payload for the registration
function and the second one to act as trace mem emitters a.k.a
provider payload.

When it is used as provider payload, those function copy the trace
field to trace memory based on the tracing mode.

Added payload definitions under ALLOW_EXPERIMENTAL_API define
to allow the existing applications to compile without enabling
experimental APIs.

0cd4ea043f trace: implement registration payload
The trace function payloads such as rte_trace_point_emit_* have
dual functions. The first to emit the payload for the registration
function and the second one to act as trace memory emitters.

When it is used as registration payload, it will do the following to
fulfill the registration job.
- Find out the size of the event,
- Generate metadata field string using __rte_trace_point_emit_field().

29d985cad8 trace: implement memory allocation
Trace memory will be allocated per thread to enable lockless trace
events updates to the memory. The allocator will first attempt to
allocate from hugepage, then if not available from hugepage or
finally fallback to malloc memory.

Later in the patches series, this API will be hooked to DPDK fast path
and control plane thread creation API. It is possible for non
DPDK thread to use trace events. In that case, trace memory
will be allocated on the first event emission.
