- * Flow rule attributes.
- *
- * Priorities are set on two levels: per group and per rule within groups.
- *
- * Lower values denote higher priority, the highest priority for both levels
- * is 0, so that a rule with priority 0 in group 8 is always matched after a
- * rule with priority 8 in group 0.
- *
- * 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).
- *
- * Group and 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.
