59e657aa0b net/enic: add missing Tx offload flags
The following commit has added a number of existing offload flags such
as PKT_TX_IPV4 and PKT_TX_IPV6 to PKT_TX_OFFLOAD_MASK defined in
rte_mbuf.h. That change breaks the enic driver's Tx prepare handler.

commit ef28cfa73822 ("mbuf: fix Tx offload mask")

The enic driver keeps the supported offload flags in a local variable
(tx_offload_mask), which is strictly a subset of
PKT_TX_OFFLOAD_MASK. This variable is then used to compute the
unsupported flags (tx_offload_notsup_mask), and the Tx prepare handler
(tx_pkt_prepare) uses it to reject packets with unsupported offload
flags.

As is, tx_offload_notsup_mask ends up containing flags like
PKT_TX_IPV4 that are actually supported by the driver, which then
breaks any application that uses checksum offloads and calls the Tx
prepare handler. So add the flags to tx_offload_mask that the driver
supports but were missing in PKT_TX_OFFLOAD_MASK.

432ed10d81 net/enic: fix supported packet types
The handler for dev_supported_ptypes_get currently returns null when

types. Add the missing packet types to the supported list, and return
the right list for the vectorized Rx handler.

85fea26693 examples/kni: improve zeroing statistics
The worker threads incrementing the rx/tx_packets race with the signal
handler from the main thread zeroing the entire statistics structure.
This can cause the statistics to fail to be zeroed, even when there
is no traffic on those interfaces.

Improve zeroing the statistics by only incrementing rx/tx_packets
in worker threads by a non-zero amount.  This limits the race to the
periods in which traffic is actually being received or transmitted.

Add module parameter 'carrier='on|off' to set the default carrier state
for linux network interfaces created by the KNI module.  The default
carrier state is 'off'.

For KNI interfaces which need to reflect the carrier state of
a physical Ethernet port controlled by the DPDK application, the
default carrier state should be left set to 'off'.  The application
can set the carrier state of the KNI interface to reflect the state
of the physical Ethernet port using rte_kni_update_link().

For KNI interfaces which are purely virtual, the default carrier
state can be set to 'on'.  This enables the KNI interface to be
used without having to explicity set the carrier state to 'on'
using rte_kni_update_link().

e605a1d36c hash: add lock-free r/w concurrency
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.

9d033dac7d hash: support no free on delete
rte_hash_lookup_xxx APIs return the index of slot in
the key store. Application(reader) can use that index to reference
other data structures in its scope. Because of this, the
index should not be freed till the application completes
using the index.
RTE_HASH_EXTRA_FLAGS_NO_FREE_ON_DEL is introduced to support this.
When this flag is enabled rte_hash_del_xxx APIs do not free the
key-store index/internal memory associated with the deleted
entry. The new API rte_hash_free_key_with_position should be called
to free the key-store index/internal memory after calling
rte_hash_del_xxx APIs.

40f8e9c28c hash: separate multi-writer from r/w concurrency
RW concurrency is required with single writer and multiple reader
usecase as well. Hence, multi-writer should not be enabled by default when
RW concurrency is enabled.

e013078857 examples/power: support meson/ninja build
Add meson.build in vm_power_manager and the guest_cli subdirectory.
Building can be achieved by going to the build directory, and using

meson configure -Dexamples=vm_power_manager,vm_power_manager/guest_cli

Then, when ninja is invoked, it will build dpdk-vm_power_manger and
dpdk-guest_cli

Work still needs to be done on the meson build system to handles the case
where the target list of example apps is defined as 'all'. That will come
in a future patch.

a63504a90f examples/power: add JSON string handling
Add JSON string handling to vm_power_manager for JSON strings received
through the fifo. The format of the JSON strings are detailed in the
next patch, the vm_power_manager user guide documentation updates.

This patch introduces a new dependency on Jansson, a C library for
encoding, decoding and manipulating JSON data. To compile the sample app
you now need to have installed libjansson4 and libjansson-dev (these may
be named slightly differently depending on your Operating System)
