app/testpmd: fix queue offload configuration

When adding offloads from commandline, not only port
related configuration bits should be set, but also queue
related offloads configuration bits, or it will cause error.
For example, test in this process for ixgbe:
(1)./x86_64-native-linuxapp-gcc/app/testpmd -c 0x6 -n 4
-- -i --portmask=0x1 --port-topology=loop --disable-crc-strip
(2)port stop all
(3)port config all crc-strip on
(4)port start all
we will see "Fail to configure port 0 rx queues" of warning info.

app/testpmd: fix parsing RSS queue rule

Declare a local variable 'arg' to hold the pointer to ARGS_ENTRY_ARB,
otherwise, the pop 'arg' in 'parse_int' holds wrong data like 'arg->
offset = 5912737, arg->size = 0', this caused the parse failure.

If calling like 'push_args(ctx, ARGS_ENTRY_ARB..)', the below code for
assigning 'offset & size' will be missed for some gcc optimization.

net/mlx5: check memory allocation in flow creation

rte_calloc functions returns a non-null pointer in case of

net/mlx5: fix condition for link update fallback

mlx5_link_update uses the newer ethtool command
ETHTOOL_GLINKSETTINGS to determine interface capabilities but falls
back to the older (deprecated) ETHTOOL_GSET command if the new
method fails for any reason.
The older method only supports reporting of capabilities up to 40G.

However, mlx5_link_update_unlocked_gs can return a failure for a
number of reasons (including the link being down).
Using the older method in cases of transient failure of the method
can result in reporting of reduced capabilities to the application.

The older method (mlx5_link_update_unlocked_gset) should only be
invoked if the newer method returns EOPNOTSUPP.

timer: fix resource leak in finalize

Currently, whenever timer library is initialized, the memory
is leaked because there is no telling when primary or secondary
processes get to use the state, and there is no way to
initialize/deinitialize timer library state without race
conditions [1] because the data itself must live in shared memory.

Add a spinlock to the shared mem config to have a way to
exclusively initialize/deinitialize the timer library without
any races, and implement the synchronization mechanism based
on this lock in the timer library.

Also, update the API doc. Note that the behavior of the API
itself did not change - the requirement to call init in every

bus/pci: consider only usable devices for IOVA mode

heuristic ("are devices bound?", "are devices bound to UIO?", "are pmd
drivers supporting IOVA as VA?" etc..) should honor the device
white/blacklist so that an unwanted device does not impact the decision.

This applies to all OS, so implements this in common code then call a
OS specific callback.

On Linux side:
- the VFIO special considerations should be evaluated only if VFIO
  support is built,
- there is no strong requirement on using VA rather than PA if a driver

eal: compute IOVA mode based on PA availability

Currently, if the bus selects IOVA as PA, the memory init can fail when
lacking access to physical addresses.
This can be quite hard for normal users to understand what is wrong
since this is the default behavior.

Catch this situation earlier in eal init by validating physical addresses
availability, or select IOVA when no clear preferrence had been expressed.

The bus code is changed so that it reports when it does not care about
the IOVA mode and let the eal init decide.

In Linux implementation, rework rte_eal_using_phys_addrs() so that it can
be called earlier but still avoid a circular dependency with
rte_mem_virt2phys().
In FreeBSD implementation, rte_eal_using_phys_addrs() always returns
false, so the detection part is left as is.

If librte_kni is compiled in and the KNI kmod is loaded,
- if the buses requested VA, force to PA if physical addresses are
  available as it was done before,
- else, keep iova as VA, KNI init will fail later.
