Distribute the tx queues evenly across all queue groups. This will
help the queues to get more equal sharing among the queues when all
are in use.
In the previous algorithm, the next queue group node will be picked up
only after the previous one filled with max children.
For example: if VSI is configured with 9 queues, the first 8 queues
will be assigned to queue group 1 and the 9th queue will be assigned to
queue group 2.
The 2 queue groups split the bandwidth between them equally (50:50).
The first queue group node will share the 50% bandwidth with all of
its children (8 queues). And the second queue group node will share
the entire 50% bandwidth with its only children.

ice_set_fc takes a u8 pointer 'aq_failures' as an input parameter. If

If the caller does not initialize this variable to 0 before calling

The capability flags used to report whether an NVM component has
a pending update are stored as simple booleans. If ice_parse_caps finds
the relevant capability then the boolean is set to true.
If the capability is not provided by firmware, then the boolean value
will be left alone. This works during initialization because the
capabilities structure is zero-initialized.
However, this does not work if capabilities are updated by calling
ice_get_caps again after driver load. For example, consider if firmware
had a pending update, and then an EMPR was triggered. The update will
complete, and firmware will no longer report these capabilities.
However, the device driver will have already set the pending flags.
After an EMPR, new capabilities are read. However, because the pending
flags in the dev_caps.common_cap structure have already been set, they
will remain true.
Fix this by clearing the capabilities structures in ice_parse_caps
before processing any capabilities.
This ensures that the capabilities structure will always be refreshed to
match the state of the device or function capabilities reported by
firmware.

PCI function with disabled DV support
mlx5_ipool_cfg[MLX5_IPOOL_MLX5_FLOW].size was reduced to match legacy
verbs flow size. Since mlx5_ipool_cfg[MLX5_IPOOL_MLX5_FLOW] is a
global variable that change reflected on DV enabled MLX5 PCI functions
too.
Running flow with invalid ipool size crashes PMD.
The patch adjusts ipool flow size for each active PCI function.

When capturing packets into a PCAP file, DPDK currently uses
microseconds for the timestamps. But libpcap supports interpreting
tv_usec as nanoseconds depending on the file timestamp precision,
as of commit ba89e4a18e8b ("Make timestamps precision configurable").
To support this, use PCAP_TSTAMP_PRECISION_NANO when creating the
empty PCAP file as specified by PCAP_OPEN_DEAD(3PCAP) and implement
nanosecond timeval addition. This also ensures that the precision
reported by capinfos is nanoseconds (9).
Note that NSEC_PER_SEC is defined as 1000000000L instead of 1e9 since
the latter might be interpreted as floating point.

There is a coverity defect related "Unchecked return value".
The internal static hns3_reset_err_handle function is reset error
process of hns3 PMD driver. If failure in reset process, it does not
mean that the network port is completely unavailable, so the command
interface between driver and firmware still needs to be initialized.
Regardless of whether the execution of the function named hns3_cmd_init
is successful or not, the next process after execution must be
continued, so there is no need to check the return value. If
hns3_cmd_init fails to execute, there will be corresponding log
information inside hns3_cmd_init.

Currently, when flow destroyed, some memory resources may still be kept
as cached to help next time create flow more efficiently.
Some system may need the resources to be more flexible with flow create
and destroy. After peak time, with millions of flows destroyed, the
system would prefer the resources to be reclaimed completely, no cache
is needed. Then the resources can be allocated and used by other
components. The system is not so sensitive about the flow insertion
rate, but more care about the resources.
Both DPDK mlx5 PMD driver and the low level component rdma-core have
provided the flow resources to be configured cached or not, but there is
no APIs or parameters exposed to user to configure the flow resources
cache mode. In this case, introduce a new PMD devarg to let user
configure the flow resources cache mode will be helpful.
This commit is to add a new "reclaim_mem_mode" to help user configure if
the destroyed flows' cache resources should be kept or not.
Their will be three mode can be chosen:
1. 0(none). It means the flow resources will be cached as usual. The
resources will be cached, helpful with flow insertion rate.
2. 1(light). It will only enable the DPDK PMD level resources reclaim.
3. 2(aggressive). Both DPDK PMD level and rdma-core low level will be
configured as reclaimed mode.
With these three mode, user can configure the resources cache mode with
different levels.

The original code would deadlock itself if a link change event
happened with link state interrupt enabled. The problem is that
the link state changed message would be seen while reading
the host to guest ring (under lock) and then the driver would
send a query to the host to see the new link state. The response
would never be seen (stuck in a while loop) waiting for the
response.
The solution is to use the link change indication to trigger
a DPDK alarm. The alarm will happen in a different thread and
in that context it can send request for new link state and
also do interrupt callback. This is similar to how the bonding
driver is handling the same thing.
