The patch changes rx_burst profiling approach:
1. VTune's instrumentation is removed
2. empty hook callback for profiling is added
This way all VTune-specific logic moves to the VTune side.
Hook is enabled only when CONFIG_RTE_ETHDEV_PROFILE_WITH_VTUNE option
is turned on. VTune uses this hook to attach to the polling cycle. It
is not possible to attach to the rx_burst directly, as it is inline.

Due to the upcoming external memory support [1], some API and ABI
changes will be required. In addition, although the changes called
out in the deprecation notice are not yet present in form of code
in the published RFC itself, they are based on consensus on the
mailing list [2] on how to best implement this feature.

l2fwd_fork relies on a multiprocess model that DPDK does not support
(calling rte_eal_init() before fork()), in particular in light of recent
EAL changes like the multiproess communication channel.
This example can mislead users into thinking this is a supported
multiprocess model; hence, this commit removes this example and the
corresponding user guide documentation as well.

This reverts the patch that enabled mbuf fast free.
There are two main reasons.
First, enic_fast_free_wq_bufs is broken. When
DEV_TX_OFFLOAD_MBUF_FAST_FREE is enabled, the driver calls this
function to free transmitted mbufs. This function currently does not
reset next and nb_segs. This is simply wrong as the fast-free flag
does not imply anything about next and nb_segs.
We could fix enic_fast_free_wq_bufs by making it to call
rte_pktmbuf_prefree_seg to reset the required fields. But, it negates
most of cycle saving.
Second, there are customer applications that blindly enable all Tx
offloads supported by the device. Some of these applications do not
satisfy the requirements of mbuf fast free (i.e. a single pool per
queue and refcnt = 1), and end up crashing or behaving badly.

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
Stephen [1], this patch introduces a new dependency to libmnl [2]
(LGPL-2.1) when compiling mlx5.

Due to the complex NVGRE_ENCAP flow action and based on the fact testpmd
does not allocate memory, this patch adds a new command in testpmd to
initialise a global structure containing the necessary information to
make the outer layer of the packet. This same global structure will
then be used by the flow command line in testpmd when the action
nvgre_encap will be parsed, at this point, the conversion into such
action becomes trivial.
This global structure is only used for the encap action.
