net/mlx5: modify hash Rx queue objects

Implement modification for hashed table of Rx queue object (see
mlx5_hrxq_modify()). This implementation relies on the capability to
modify TIR object via DevX API, i.e. current implementation doesn't
support verbs HW object operations. The functionality to modify hashed
table of Rx queue object is prerequisite to implement
rete_flow_shared_action_update() for shared RSS action in mlx5 PMD.

net/ice: update writeback policy to reduce latency

Just like iavf, setting the value to 2us allows for generally good
streaming packet performance while keeping latency down, and
generally keeps the performance of the PF and VF interfaces similar.

net/iavf: fix performance with writeback policy

The iavf driver was trying to use writeback on ITR, but was
never setting an ITR, so it didn't work. This caused performance
to be limited due to too much PCIe traffic and partial writes
during most benchmarking workloads.
Set the ITR during queue setup, which can be checked at runtime
by reading register 0x2800. Setting the value to 2us allows
for generally good streaming packet performance while keeping

raw/ifpga/base: enhance driver reliability in multi-process

Current hardware protection is based on pthread mutex which
work just for situation of multi-thread in one process. In
multi-process environment, hardware state machine would be
corrupted by concurrent access, that means original pthread
mutex mechanism need be enhanced.

The major modifications in this patch are list below:
1. Create a mutex for adapter in shared memory named
   "mutex.IFPGA:domain:bus:dev.func" when device is probed.
2. Create a shared memory named "IFPGA:domain:bus:dev.func" during opae
   adapter is initializing. There is a reference count in shared memory.
   Shared memory will be destroyed once reference count turned to zero.
3. Two mutexs are created in shared memory and initialized with flag
   PTHREAD_PROCESS_SHARED. One for SPI and the other for I2C. They will
   be passed to SPI and I2C driver subsequently.
4. DTB data in flash will be cached in shared memory. Then MAX10 driver
   can read DTB from shared memory instead of flash. This avoid
   confliction of concurrent flash access between hardware and software.

Also 'opae_adapter_free()' is removed from 'ifpga_rawdev_destroy()',

app/testpmd: fix RSS key for flow API RSS rule

When a flow API RSS rule is issued in testpmd, device RSS key is changed
unexpectedly, device RSS key is changed to the testpmd default RSS key.

Consider the following usage with testpmd:
1. first, startup testpmd:
 testpmd> show port 0 rss-hash key
 RSS functions: all ipv4-frag ipv4-other ipv6-frag ipv6-other ip
 RSS key: 6D5A56DA255B0EC24167253D43A38FB0D0CA2BCBAE7B30B477CB2DA38030F
          20C6A42B73BBEAC01FA
2. create a rss rule
 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end \
          actions rss types ipv4-udp end queues end / end

3. show rss-hash key
 testpmd> show port 0 rss-hash key
 RSS functions: all ipv4-udp udp
 RSS key: 74657374706D6427732064656661756C74205253532068617368206B65792
          C206F76657272696465

This is because testpmd always sends a key with the RSS rule,
if user provides a key as part of the rule that key is used, if user
doesn't provide a key, testpmd default key is sent to the PMDs, which is
causing device programmed RSS key to be changed.

There was a previous attempt to fix the same issue [1], but it has been
reverted back [2] because of the crash when 'key_len' is provided
without 'key'.

This patch follows the same approach with the initial fix [1] but also
addresses the crash.

After change, testpmd RSS key is 'NULL' by default, if user provides a
key as part of rule it is used, if not no key is sent to the PMDs at all
