Dekel Peled 09315fc838 ethdev: add VLAN attributes to ethernet and VLAN items 
This patch implements the change proposes in RFC [1], adding dedicated
fields to ETH and VLAN items structs, to clearly define the required
characteristic of a packet, and enable precise match criteria.
Documentation is updated accordingly.

* Flow rule attributes.
*
* Priorities are set on a per rule based within groups.
*
* Lower values denote higher priority, the highest priority for a flow rule
* is 0, so that a flow that matches for than one rule, the rule with the
* lowest priority value will always be matched.
*
* Although optional, applications are encouraged to group similar rules as
* much as possible to fully take advantage of hardware capabilities
* (e.g. optimized matching) and work around limitations (e.g. a single
* pattern type possibly allowed in a given group). Applications should be
* aware that groups are not linked by default, and that they must be
* explicitly linked by the application using the JUMP action.
*
* Priority levels are arbitrary and up to the application, they
* do not need to be contiguous nor start from 0, however the maximum number
* varies between devices and may be affected by existing flow rules.
*
* If a packet is matched by several rules of a given group for a given
* priority level, the outcome is undefined. It can take any path, may be
* duplicated or even cause unrecoverable errors.
*
* Note that support for more than a single group and priority level is not
* guaranteed.
*
* Flow rules can apply to inbound and/or outbound traffic (ingress/egress).
*
* Several pattern items and actions are valid and can be used in both
* directions. Those valid for only one direction are described as such.
*
* At least one direction must be specified.
*
* Specifying both directions at once for a given rule is not recommended
* but may be valid in a few cases (e.g. shared counter).

* Matching pattern item definition.
*
* A pattern is formed by stacking items starting from the lowest protocol
* layer to match. This stacking restriction does not apply to meta items
* which can be placed anywhere in the stack without affecting the meaning
* of the resulting pattern.
*
* Patterns are terminated by END items.
*
* The spec field should be a valid pointer to a structure of the related
* item type. It may remain unspecified (NULL) in many cases to request
* broad (nonspecific) matching. In such cases, last and mask must also be
* set to NULL.
*
* Optionally, last can point to a structure of the same type to define an
* inclusive range. This is mostly supported by integer and address fields,
* may cause errors otherwise. Fields that do not support ranges must be set
* to 0 or to the same value as the corresponding fields in spec.
*
* Only the fields defined to nonzero values in the default masks (see
* rte_flow_item_{name}_mask constants) are considered relevant by
* default. This can be overridden by providing a mask structure of the
* same type with applicable bits set to one. It can also be used to
* partially filter out specific fields (e.g. as an alternate mean to match
* ranges of IP addresses).
*
* Mask is a simple bit-mask applied before interpreting the contents of
* spec and last, which may yield unexpected results if not used
* carefully. For example, if for an IPv4 address field, spec provides
* 10.1.2.3, last provides 10.3.4.5 and mask provides 255.255.0.0, the
* effective range becomes 10.1.0.0 to 10.3.255.255.
