net/mlx5: introduce buffer size parameter for hairpin

When creating a hairpin queue, the total data size and the maximal
number of packets are interrelated. The differ is the stride size.
Larger buffer size means big packet like jumbo could be supported,
but in the meanwhile, it will introduce more cache misses and have a
side effect on the performance.
Now a new device parameter "hp_buf_log_sz" is introduced for
applications to set the total data buffer size (the logarithm value).
Then the maximal number of packets will also be calculated
automatically by this value.
Applications could also change this value to a larger one in order
to support larger packets in hairpin case. A smaller value will be
beneficial for memory consumption.
If it is not set, the default value will be used.

net/mlx5: check device status before creating flow

By default, flows are categorized into two types of a mlx5 device.
  1. The PMD driver will create some default flows to enable the

     this is transparent to the upper layer application.
  2. Other flows will be created in the application based on its
     needs.
When in the old cached mode for application flows, it is allowed
to created the flow before the device is started. And when
starting the device, all the flows will be applied to the hardware
and take effect. The cached flows will be also applied in the same
time.
In non-cached mode, all the flows will never be cached when stopping

before it is started. Default flows owned by PMD driver are not

performed by order.

Relaxed Ordering is a PCI optimization which by enabling it
we allow the system to perform read/writes in a different
order without having to wait for completion and improve
the performance in that matter.

This commit introduces the creation of relaxed ordering
memory regions in mlx5.
As relaxed ordering is an optimization, drivers that
do not support it can simply ignore it and therefore
it is enabled by default.

net/mlx5: fix validation of VXLAN/VXLAN-GPE specs

Trying to create zero spec for vni wasn't allowed, to
avoid matching all packets from previous layer (udp).
This behavior is incorrect, since VXLAN is being identified
through the outer UDP destination port.

Currently, if the user didn't specify outer UDP destination
port the PMD will automatically match only on  outer
UDP port of 4798, and if the user want to match on some none
standard port he need to specify it explicitly in the rule.

This removes the limitation of vni spec to be able to match any
vni.

net/ice/base: store NVM version in extracted format

Currently the NVM and Option ROM version information is stored in
a minimal format. The ice_get_nvm_version function exists to extract
this information for display.

This needlessly complicates using these fields as the extraction
function must be called to parse the NVM and Option ROM data. Further
confusion occurs because the prefix of "oem_" is used for the Option
ROM version. This appears to have been done because the Option ROM data
was requested for display by OEMs.

Refactor this code so that the NVM version and Option ROM version
components are extracted immediately.

Introduce a new struct ice_orom_info which will store the Option ROM
major, build, and patch numbers. Introduce the new major_ver and
minor_ver fields to store the NVM version in its high and low byte
components.

Remove the ice_get_nvm_version function. Instead, use the same logic to
convert the fields read from the NVM into the extracted format.

This simplifies use of these fields as they will be stored already

Adds functions to check for link override firmware support and get
the override settings for a port. Link override allows a user to force
link settings that are not normally supported.

Firmware support is version dependent so a function to check support has
been added.

The link FC settings will use the override if available.

net/ice/base: minor fixes

This is a collection of minor fixes that were found during code review.
Changes are:
- Call ice_hweight8() instead of calculating it ourselves in
  ice_bits_max_set().
- Call ice_test_and_clear_bit() over calling ice_is_bit_set() then
  ice_clear_bit() in ice_rem_vsi_rss_list().
- Remove 'chrs' variable in ice_add_prof_id_flow() as it's not being
  used for anything.
- Return result directly instead of assigning to variable then
  returning the variable in ice_rem_vsig().
- Reduce scope, and don't initialize, 'or_vsig' in
  ice_add_prof_id_flow().
- Return error immediately in ice_add_prof_id_vsig(). Since the memory
  wasn't allocated, there is no need to goto and attempt to free memory.
- Show that values 37-38 are reserved in ice_flow_avf_hdr_field as the
  other reserved values are shown.
- Fix RCT ordering
- Remove initialization of values that aren't needed
- Fix function headers to match function names
- Use offsetof instead of calculating ourselves in ice_pkg_buf_alloc()
- In ice_rem_prof(), do not set status to ICE_SUCCESS as, due to code
  flow, this will always be ICE_SUCCESS.
- Remove unnecessary semicolon in ice_prof_gen_key()
- Remove unnecessary initializations
- correct bw_alloc type in ice_sched_add_root_node

net/ice/base: fix uninitialized stack variables

Via code inspection, I found that some partially initialized

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.

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.

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.
