ffb3389cef net/dpaa2: use hash FLCTYPE only for LX2
Enabling hash results in FD requires setting DPNI_FLCTYPE_HASH in
dpni_set_offload API. Setting this FLCTYPE for DPNI sets the FD[SC]
to 0 for LS2 in the hardware thus disabling data/annotation stashing.
For LX2 this is fixed in hardware and thus hash result and parse
results can be received in FD using this option.

496324d2a5 bus/fslmc: add flag to configure DCA in QBMAN multi Tx
With the current QBMAN multi-tx API, we need to create separate
enqueue descriptors for each of the packet which is required to
be enqueued to the hardware, once we support Atomic Queues
(with DCA) in dpaa2 drivers. Creating enqueue descriptor for
each packet is costly and have significant performance impact.
This patch introduces a flag parameter in the QBMAN multi-tx API,
so that DCA configuration (and later on ORP/ODP for ordered queues)
can be passed using flags and be updated in the EQCR using this flag.

0d440d081c lib: fix missing includes in exported headers
Many exported headers rely on definitions found in rte_config.h without
including it, as shown by the following command:

 grep -L '^#include <rte_config.h>' -- \
  $(grep -Rl \
    $(sed -n '/^#define \([^ ]\+\).*$/{s//\1/;H;};${x;s/\n//;s/\n/\\|/g;p;}' \
      build/include/rte_config.h) \
    -- build/include/)

We cannot assume external applications will include rte_config.h on their
own, neither directly nor through a -include parameter like DPDK does
internally.

This not only causes obvious compilation failures that can be reproduced
with check-includes.sh such as:

 [...]/rte_memory.h:88:43: error: ‘RTE_CACHE_LINE_SIZE’ was not declared in
     this scope
  #define __rte_cache_aligned __rte_aligned(RTE_CACHE_LINE_SIZE)
                                            ^

It also results in less visible issues, for instance rte_hash_crc.h relying
on RTE_ARCH_X86_64's presence to provide dedicated inline functions.

This patch partially reverts the commit below and adds missing include
lines to the remaining files.

a2efa4f660 net/e1000: always enable receive and transmit
The transmit and receive controller state machines are only enabled after
receiving an interrupt and the link status is now valid.  If an adapter
is being used in conjunction with NC-SI, network controller sideband
interface, the adapter may never get a link state change interrupt since
the adapter's PHY is always link up and never changes state.

To fix this, always enable and disable the transmit and receive with
.dev_start and .dev_stop.  This is a better match for what is typically
done with the other PMD's.  Since we may never get an interrupt to check
the link state, we also poll once at the end of .dev_start to get the
current link status.

d732ec19dc net/tap: remove unused kernel version definitions
The TAP device does not use these definitions in current version.
And kernel version is not the correct way to detect features.

8052bbd9d5 net/failsafe: improve Rx sub-devices iteration
Connecting the sub-devices each other by cyclic linked list can help to
iterate over them by Rx burst functions because there is no need to
check the sub-devices ring wraparound.

Create the aforementioned linked-list and change the Rx burst functions
iteration accordingly.

1e2670a900 net/failsafe: mitigate data plane atomic operations
Fail-safe uses atomic operations to protect sub-device close operation
calling by host thread in removal time while the removed sub-device
burst functions are still in process by application threads.

Using "set" atomic operations is a little bit more efficient than "add"
or "sub" atomic operations because "set" shouldn't read the value and
in fact, it does not need a special atomic mechanism in x86 platforms.

Replace "add 1" and "sub 1" atomic operations by "set 1" and "set 0"
atomic operations.

e628228309 net/failsafe: fix Rx safe check compiler hint
failsafe_rx_burst function is used when there are no sub-devices or at
least one of them has been removed, on the other hand, when all the
sub-devices are present, failsafe_rx_burst_fast function is used.

So it's really expected that some of the sub-devices will be unsafe for
Rx burst in failsafe_rx_burst execution.

Remove unlikely compiler hint from fs_rx_unsafe calling.
