service: improve checks of coremasks

This commit improves the error checking performed on the
core masks (or lists) of the service cores, in particular
with respect to the data-plane (RTE) cores of DPDK.

With this commit, invalid configurations are detected at
runtime, and warning messages are printed to inform the user.

For example specifying the coremask as 0xf, and the service
coremask as 0xff00 is invalid as not all service-cores are
contained within the coremask. A warning is now printed to

app/testpmd: revert softnic integration in CLI thread

This patch reverts the testpmd CLI prompt routine modifications done
in order to support softnic.
The reason of doing so is due to testpmd abnormal exit observed on
several setups caused by the softnic modifications to this routine,
for example: When running testpmd with tap interface
(testpmd

 --mbcache=512 -i --nb-cores=7 --rxq=2 --txq=2 --txd=512
 --rxd=512 --port-topology=chained --forward-mode=rxonly)
testpmd crashes seconds after presenting its prompt with the following
error:
  testpmd> PANIC in prompt():
  CLI poll error (-1)

  Thread 1 "testpmd" received signal SIGABRT, Aborted.

  #2  0x0000000000468027 in __rte_panic ()
  #3  0x00000000004876ed in prompt ()
  #4  0x000000000046dffc in main ()

When running testpmd with bare-metal device
(testpmd -n 4 --socket-mem=1024,1024 -w 04:00.0  --
 --burst=64 --mbcache=512 -i --nb-cores=7
 --rxq=64 --txq=4 --txd=16 --rxd=16)
and pressing CTRL+D right after testpmd prompt is presented then
the program crashes while presenting the same messages as above.

Needless to say that this behavior is not observed when using the

net/mlx5: add framework for switch flow rules

Because mlx5 switch flow rules are configured through Netlink (TC
interface) and have little in common with Verbs, this patch adds a separate
parser function to handle them.

- mlx5_nl_flow_transpose() converts a rte_flow rule to its TC equivalent
  and stores the result in a buffer.

- mlx5_nl_flow_brand() gives a unique handle to a flow rule buffer.

- mlx5_nl_flow_create() instantiates a flow rule on the device based on
  such a buffer.

- mlx5_nl_flow_destroy() performs the reverse operation.

These functions are called by the existing implementation when encountering
flow rules which must be offloaded to the switch (currently relying on the
transfer attribute).

net/mlx5: lay groundwork for switch offloads

With mlx5, unlike normal flow rules implemented through Verbs for traffic
emitted and received by the application, those targeting different logical
ports of the device (VF representors for instance) are offloaded at the
switch level and must be configured through Netlink (TC interface).

This patch adds preliminary support to manage such flow rules through the
flow API (rte_flow).

Instead of rewriting tons of Netlink helpers and as previously suggested by
