d6fe2f5ee0 app/test: fix missing NULL pointer checks
In test_sched, we are missing NULL pointer checks after create_mempool()
and rte_pktmbuf_alloc(). Add in these checks using TEST_ASSERT_NOT_NULL macros.

VERIFY macro was removed and replaced by standard test ASSERTS from "test.h" header.
This provides additional information to track when the failure occurred.

23df14d1ba devargs: restore empty devargs
Following commit c07691ae10, an implicit change has been done in the
devargs API.
This triggers problem in virtual pmds that did not check for parameters
validity as it was implicitely valid.

Fix this by restoring the empty argument as "" and add a note in the api.
Restore associated tests.

Fixes: c07691ae10 ("devargs: remove limit on parameters length")

If disabled, the parsing of the csum forward engine stops at the first

e20511e4b2 app/testpmd: force user to stop forwarding when changing port/core list
Testpmd has the capability of changing the forwarding cores and ports in runtime.
If these are changed when forwarding, two issues may be encountered:

- If "show config fwd" is used, changes made in the core list are applied.
  Therefore, trying to stop forwarding may hang testpmd,
  since it could be waiting for cores to stop that are not actually running anything

- If the port list is changed, when stopping forwarding,
  it may miss the stats of some of the ports that were actually being used.

ecd9d5193b bond: remove offload flags from transmit policy checks
The Link bonding library is incorrectly using receive packet type flags
in the transmit policy hashing functions, which would cause packets
generated locally to be incorrectly distributed across the slave
devices. This patch completely removes the dependency on the packet
type flags and uses the ether_type from either the Ethernet header or
the VLAN headers for branching.

This patch also includes the associate changes in the test suite and in
the packet_burst_generator code to remove the dependences on the packet
type flags.

7e60e08397 acl: remove standalone header
This is a duplication of some EAL parts for a standalone packaging
which is not documented.
Packaging should be done outside of DPDK.

62945e029e acl: introduce config parameter for performance/space trade-off
If at build phase we don't make any trie splitting,
then temporary build structures and resulting RT structure might be
much bigger than current.
>From other side - having just one trie instead of multiple can speedup
search quite significantly.
>From my measurements on rule-sets with ~10K rules:
RT table up to 8 times bigger, classify() up to 80% faster
than current implementation.
To make it possible for the user to decide about performance/space trade-off -
new parameter for build config structure (max_size) is introduced.
Setting it to the value greater than zero, instructs  rte_acl_build() to:
- make sure that size of RT table wouldn't exceed given value.
- attempt to minimise number of tries in the table.
Setting it to zero maintains current behaviour.
That introduces a minor change in the public API, but I think the possible
performance gain is too big to ignore it.
