5b4efcc6b9 ethdev: expose flow API error helper
rte_flow_error_set() is a convenient helper to initialize error objects.

Since there is no fundamental reason to prevent applications from using it,
expose it through the public interface after modifying its return value
from positive to negative. This is done for consistency with the rest of
the public interface.

Documentation is updated accordingly.

f8244c6399 ethdev: increase port id range
Extend port_id definition from uint8_t to uint16_t in lib and drivers
data structures, specifically rte_eth_dev_data. Modify the APIs,
drivers and app using port_id at the same time.

Fix some checkpatch issues from the original code and remove some
unnecessary cast operations.

release_17_11 and deprecation docs have been updated in this patch.

323f811a4a ethdev: add isolated mode to flow API
Isolated mode can be requested by applications on individual ports to avoid
ingress traffic outside of the flow rules they define.

Besides making ingress more deterministic, it allows PMDs to safely reuse
resources otherwise assigned to handle the remaining traffic, such as
global RSS configuration settings, VLAN filters, MAC address entries,
legacy filter API rules and so on in order to expand the set of possible
flow rule types.

To minimize code complexity, PMDs implementing this mode may provide
partial (or even no) support for flow rules when not enabled (e.g. no
priorities, no RSS action). Applications written to use the flow API are
therefore encouraged to enable it.

Once effective, leaving isolated mode may not be possible depending on PMD
implementation.

a757583e55 ethdev: modify flow API error function
Based on initial PMD implementations of the flow API, returning the error
structure which may be NULL is useless and always discarded.

Returning the error code instead appears to be much more convenient.

b1a4b4cbc0 ethdev: introduce generic flow API
This new API supersedes all the legacy filter types described in
rte_eth_ctrl.h. It is slightly higher level and as a result relies more on
PMDs to process and validate flow rules.

Benefits:

- A unified API is easier to program for, applications do not have to be
  written for a specific filter type which may or may not be supported by
  the underlying device.

- The behavior of a flow rule is the same regardless of the underlying
  device, applications do not need to be aware of hardware quirks.

- Extensible by design, API/ABI breakage should rarely occur if at all.

- Documentation is self-standing, no need to look up elsewhere.

Existing filter types will be deprecated and removed in the near future.
