Add lock-free read-write concurrency. This is achieved by the
following changes.
1) Add memory ordering to avoid race conditions. The only race
condition that can occur is - using the key store element
before the key write is completed. Hence, while inserting the element
the release memory order is used. Any other race condition is caught
by the key comparison. Memory orderings are added only where needed.
For ex: reads in the writer's context do not need memory ordering
as there is a single writer.
key_idx in the bucket entry and pdata in the key store element are
used for synchronisation. key_idx is used to release an inserted
entry in the bucket to the reader. Use of pdata for synchronisation
is required due to updation of an existing entry where-in only
the pdata is updated without updating key_idx.
2) Reader-writer concurrency issue, caused by moving the keys
to their alternative locations during key insert, is solved
by introducing a global counter(tbl_chng_cnt) indicating a
change in table.
3) Add the flag to enable reader-writer concurrency during
run time.

Add the support for new traffic pattern aware power control
power management API.
Example:
./l3fwd-power -l xxx -n 4 -w 0000:xx:00.0 -w 0000:xx:00.1 -- -p 0x3
-P --config="(0,0,xx),(1,0,xx)" --empty-poll="0,0,0" -l 14 -m 9 -h 1
Please Reference l3fwd-power document for full parameter usage
The option "l", "m", "h" are used to set the power index for
LOW, MED, HIGH power state. Only is useful after enable empty-poll
--empty-poll="training_flag, med_threshold, high_threshold"
The option training_flag is used to enable/disable training mode.
The option med_threshold is used to indicate the empty poll threshold
of modest state which is customized by user.
The option high_threshold is used to indicate the empty poll threshold
of busy state which is customized by user.
Above three option default value is all 0.
Once enable empty-poll. System will apply the default parameter if no
other command line options are provided.
If training mode is enabled, the user should ensure that no traffic
is allowed to pass through the system. When training phase complete,
the application transfer to normal operation
System will start running with the modest power mode.
If the traffic goes above 70%, then system will move to High power state.
If the traffic drops below 30%, the system will fallback to the modest
power state.
Example code use master thread to monitoring worker thread busyness.
The default timer resolution is 10ms.

1. Abstract
For packet processing workloads such as DPDK polling is continuous.
This means CPU cores always show 100% busy independent of how much work
those cores are doing. It is critical to accurately determine how busy
a core is hugely important for the following reasons:
* No indication of overload conditions.
* User does not know how much real load is on a system, resulting
in wasted energy as no power management is utilized.
Compared to the original l3fwd-power design, instead of going to sleep
after detecting an empty poll, the new mechanism just lowers the core
frequency. As a result, the application does not stop polling the device,
which leads to improved handling of bursts of traffic.
When the system become busy, the empty poll mechanism can also increase the
core frequency (including turbo) to do best effort for intensive traffic.
This gives us more flexible and balanced traffic awareness over the
standard l3fwd-power application.
2. Proposed solution
The proposed solution focuses on how many times empty polls are executed.
The less the number of empty polls, means current core is busy with
processing workload, therefore, the higher frequency is needed. The high
empty poll number indicates the current core not doing any real work
therefore, we can lower the frequency to safe power.
In the current implementation, each core has 1 empty-poll counter which
assume 1 core is dedicated to 1 queue. This will need to be expanded in the
future to support multiple queues per core.
2.1 Power state definition:
LOW: Not currently used, reserved for future use.
MED: the frequency is used to process modest traffic workload.
HIGH: the frequency is used to process busy traffic workload.
2.2 There are two phases to establish the power management system:
a.Initialization/Training phase. The training phase is necessary
in order to figure out the system polling baseline numbers from
idle to busy. The highest poll count will be during idle, where
all polls are empty. These poll counts will be different between
systems due to the many possible processor micro-arch, cache
and device configurations, hence the training phase.
In the training phase, traffic is blocked so the training
algorithm can average the empty-poll numbers for the LOW, MED and
HIGH power states in order to create a baseline.
The core's counter are collected every 10ms, and the Training
phase will take 2 seconds.
Training is disabled as default configuration. The default
parameter is applied. Sample App still can trigger training
if that's needed. Once the training phase has been executed once on
a system, the application can then be started with the relevant
thresholds provided on the command line, allowing the application
to start passing start traffic immediately
b.Normal phase. Traffic starts immediately based on the default
thresholds, or based on the user supplied thresholds via the
command line parameters. The run-time poll counts are compared with
the baseline and the decision will be taken to move to MED power
state or HIGH power state. The counters are calculated every 10ms.
3. Proposed API
1. rte_power_empty_poll_stat_init(struct ep_params **eptr,
uint8_t *freq_tlb, struct ep_policy *policy);
which is used to initialize the power management system.
2. rte_power_empty_poll_stat_free(void);
which is used to free the resource hold by power management system.
3. rte_power_empty_poll_stat_update(unsigned int lcore_id);
which is used to update specific core empty poll counter, not thread safe
4. rte_power_poll_stat_update(unsigned int lcore_id, uint8_t nb_pkt);
which is used to update specific core valid poll counter, not thread safe
5. rte_power_empty_poll_stat_fetch(unsigned int lcore_id);
which is used to get specific core empty poll counter.
6. rte_power_poll_stat_fetch(unsigned int lcore_id);
which is used to get specific core valid poll counter.
7. rte_empty_poll_detection(struct rte_timer *tim, void *arg);
which is used to detect empty poll state changes then take action.

This commit changes the hashing mechanism to "partial-key
hashing" to calculate bucket index and signature of key.
This is proposed in Bin Fan, et al's paper
"MemC3: Compact and Concurrent MemCache with Dumber Caching
and Smarter Hashing". Basically the idea is to use "xor" to
derive alternative bucket from current bucket index and
signature.
With "partial-key hashing", it reduces the bucket memory
requirement from two cache lines to one cache line, which
improves the memory efficiency and thus the lookup speed.

In use cases that hash table capacity needs to be guaranteed,
the extendable bucket feature can be used to contain extra
keys in linked lists when conflict happens. This is similar
concept to the extendable bucket hash table in packet
framework.
This commit adds the extendable bucket feature. User can turn
it on or off through the extra flag field during table
creation time.
Extendable bucket table composes of buckets that can be
linked list to current main table. When extendable bucket
is enabled, the hash table load can always achieve 100%.
In other words, the table can always accommodate the same
number of keys as the specified table size. This provides
100% table capacity guarantee.
Although keys ending up in the ext buckets may have longer
look up time, they should be rare due to the cuckoo
algorithm.

Introduce a new postcopy-support parameter to Vhost PMD that
passes the RTE_VHOST_USER_POSTCOPY_SUPPORT flag at vhost
device register time.
Flag should only be set if application does not prefault guest
memory using, for example, mlockall() syscall.
Default value is 0, meaning that postcopy support is disabled
unless specified explicitly.
Example to enable postcopy support for a given device:
--vdev 'net_vhost0,iface=/tmp/vhost-user1,postcopy-support=1'

Postcopy live-migration feature requires the application to
not populate the guest memory. As the vhost library cannot
prevent the application to that (e.g. preventing the
application to call mlockall()), the feature is disabled by
default.
The application should only enable the feature if it does not
force the guest memory to be populated.
In case the user passes the RTE_VHOST_USER_POSTCOPY_SUPPORT
flag at registration but the feature was not compiled,
registration fails.
For the same reason, postcopy and dequeue zero copy features
are not compatible, so don't advertize postcopy support if
dequeue zero copy is requested.
