@Description FM PCD API functions, definitions and enums
The FM PCD module is responsible for the initialization of all
global classifying FM modules. This includes the parser general and
common registers, the key generator global and common registers,
and the Policer global and common registers.
In addition, the FM PCD SW module will initialize all required
key generator schemes, coarse classification flows, and Policer
profiles. When An FM module is configured to work with one of these
entities, it will register to it using the FM PORT API. The PCD
module will manage the PCD resources - i.e. resource management of
Keygen schemes, etc.

@Group FM_PCD_Runtime_grp FM PCD Runtime Unit
@Description FM PCD Runtime Unit
The runtime control allows creation of PCD infrastructure modules
such as Network Environment Characteristics, Classification Plan
Groups and Coarse Classification Trees.
It also allows on-the-fly initialization, modification and removal
of PCD modules such as Keygen schemes, coarse classification nodes
and Policer profiles.
In order to explain the programming model of the PCD driver interface
a few terms should be explained, and will be used below.
* Distinction Header - One of the 16 protocols supported by the FM parser,
or one of the shim headers (1 or 2). May be a header with a special
option (see below).
* Interchangeable Headers Group- This is a group of Headers recognized
by either one of them. For example, if in a specific context the user
chooses to treat IPv4 and IPV6 in the same way, they may create an
interchangeable Headers Unit consisting of these 2 headers.
* A Distinction Unit - a Distinction Header or an Interchangeable Headers
Group.
* Header with special option - applies to ethernet, mpls, vlan, ipv4 and
ipv6, includes multicast, broadcast and other protocol specific options.
In terms of hardware it relates to the options available in the classification
plan.
* Network Environment Characteristics - a set of Distinction Units that define
the total recognizable header selection for a certain environment. This is
NOT the list of all headers that will ever appear in a flow, but rather
everything that needs distinction in a flow, where distinction is made by keygen
schemes and coarse classification action descriptors.
The PCD runtime modules initialization is done in stages. The first stage after
initializing the PCD module itself is to establish a Network Flows Environment
Definition. The application may choose to establish one or more such environments.
Later, when needed, the application will have to state, for some of its modules,
to which single environment it belongs.

@Function FM_PCD_SetNetEnvCharacteristics
@Description Define a set of Network Environment Characteristics.
When setting an environment it is important to understand its
application. It is not meant to describe the flows that will run
on the ports using this environment, but what the user means TO DO
with the PCD mechanisms in order to parse-classify-distribute those
frames.
By specifying a distinction unit, the user means it would use that option
for distinction between frames at either a keygen scheme keygen or a coarse
classification action descriptor. Using interchangeable headers to define a
unit means that the user is indifferent to which of the interchangeable
headers is present in the frame, and they want the distinction to be based
on the presence of either one of them.
Depending on context, there are limitations to the use of environments. A
port using the PCD functionality is bound to an environment. Some or even
all ports may share an environment but also an environment per port is
possible. When initializing a scheme, a classification plan group (see below),
or a coarse classification tree, one of the initialized environments must be
stated and related to. When a port is bound to a scheme, a classification
plan group, or a coarse classification tree, it MUST be bound to the same
environment.
The different PCD modules, may relate (for flows definition) ONLY on
distinction units as defined by their environment. When initializing a
scheme for example, it may not choose to select IPV4 as a match for
recognizing flows unless it was defined in the relating environment. In
fact, to guide the user through the configuration of the PCD, each module's
characterization in terms of flows is not done using protocol names, but using
environment indexes.
In terms of HW implementation, the list of distinction units sets the LCV vectors
and later used for match vector, classification plan vectors and coarse classification
indexing.
