Some devices may not support or fail setting VLAN offload
configuration based on dynamic circumstances so the
vlan_offload_set_t vector is modified to return an int so
the caller can determine success or not.
rte_eth_dev_set_vlan_offload is updated to return the
value provided by the vector when called along with restoring
the original offload configs on failure.
Existing vlan_offload_set_t vectors are modified to return
an int. Majority of cases return 0 but a few that actually
can fail now return their failure codes.
Finally, a vlan_offload_set_t vector is added to virtio
to facilitate dynamically turning VLAN strip on or off.

PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated for a while.
As explained in [1], these flags were kept to let the applications and
PMDs move to the new flag. There is also a need to support Rx vlan
offload without vlan strip (at least for the ixgbe driver).
This patch renames the old flags for this feature, knowing that some
PMDs were using PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT to indicate that
the vlan tci has been saved in the mbuf structure.
It is likely that some PMDs do not set the proper flags when doing vlan
offload, and it would be worth making a pass on all of them.

When VF reset will be supported by drivers, the API will most likely
have to return -EAGAIN to avoid blocking when the VF cannot be reset
because the PF is down.
Document it immediately even if it's not yet supported, so that users
and developers can already take into account about this use case, and
thus avoid an API-incompatible change later on.
This is based on real-world production usage and customer escalations,
using earlier patches from Intel [1].

xstats _by_id() APIs are broken because ids known by user sent directly
to the PMDs.
ethdev xstat get by id APIs:
rte_eth_xstats_get_names_by_id() and rte_eth_xstats_get_by_id()
work on ids calculated as "basic stats + extended stats"
When an application asking for id less than "basic stats count", it is
indeed asking basic stats not extended stats.
The dev_ops PMDs implements work on extended stats ids.
This patch adds a check if all requested stats are xstats and if so
converts ids to xstats ids before passing them to PMDs.
This conversion wasn't required before commit 8c49d5f1c219, because
_by_id dev_ops were always used to get whole stats via NULL ids.

of running unmapped services.
This feature is useful in cases like unit tests, where the application
code (or unit test in this case) requires accurate control over when
the service function is called to ensure correct behaviour, and when
an application has an advanced use-case and wishes to manage services
manually.

This commit adds a new function which allows an application lcore
(aka; *not* a dedicated service-lcore) to run a service. This
function is required to allow applications to gradually port
functionality to using services, while still being able to run
ordinary application functions.
This requirement became clear when a patch to the existing
eventdev/pipeline sample app was modified to use a service-core
for scheduling - and that same core should be capable of running
the "worker()" function from the application too.
This patch refactors the existing running code into a smaller
"service_run" function, which can be called by the dedicated
service-core loop, and the newly added function.

The problem is that with old QEMU versions, like v2.5, the ring
is enabled before addresses are sent, so addresses are never
translated.
This patch fixes the issue by doing the translation in
