When a cache entry is allocated by lcore A and is released by lcore B,
the driver should synchronize the cache list access of lcore A.
The design decision is to manage a counter per lcore cache that will be
increased atomically when the non-original lcore decreases the reference
counter of cache entry to 0.
In list register operation, before the running lcore starts a lookup in
its cache, it will check the counter in order to free invalid entries in
its cache.

The mlx5 internal list utility is thread safe.
In order to synchronize list access between the threads, a RW lock is
taken for the critical sections.
The create\remove\clone\clone_free operations are in the critical
sections.
These operations are heavy and make the critical sections heavy because
they are used for memory and other resources allocations\deallocations.
Moved out the operations from the critical sections and use generation
counter in order to detect parallel allocations.

When mlx5 list object is accessed by multiple cores, the list lock
counter is all the time written by all the cores what increases cache
misses in the memory caches.
In addition, when one thread accesses the list for add\remove\lookup
operation, all the other threads coming to do an operation in the list
are stuck in the lock.
Add per lcore cache to allow thread manipulations to be lockless when
the list objects are mostly reused.
Synchronization with atomic operations should be done in order to
allow threads to unregister an entry from other thread cache.

The internal mlx5 list tool is used mainly when the list objects need to
be synchronized between multiple threads.
The "cache" term is used in the internal mlx5 list API.
Next enhancements on this tool will use the "cache" term for per thread
cache management.
To prevent confusing, remove the current "cache" term from the API's
names.

For object which wants efficient index allocate and free, local
cache will be very helpful.
Two level cache is introduced to allocate and free the index more
efficient. One as local and the other as global. The global cache
is able to save all the allocated index. That means all the allocated
index will not be freed. Once the local cache is full, the extra
index will be flushed to the global cache. Once local cache is empty,
first try to fetch more index from global, if global is still empty,
allocate new trunk with more index.
This commit adds new local cache mechanism for indexed pool.

The examples for the "last_rsvd" pattern field are as below:

This flow will exactly match the last 8-bits to be 0x80.
2. ...pattern eth / ipv4 / udp / vxlan last_rsvd spec 0x80

For the newly attached ports (with "port attach" command) the

line, were not applied, causing port start failure following
the attach.
For example, if scattering offload was configured in command
line and rxpkts was configured for multiple segments, the newly
attached port start was failed due to missing scattering offload
enable in the new port settings. The missing code to apply
the offloads to the new device and its queues is added.
