Due to limited resources of X*710 (parser and analyzer configuration
tables, number of packet classification types, number of packet types,
filters configuration tables, etc.), it's impossible to simultaneously
support all protocols/filters required for different parts on network.
To enable protocols/filters extensions for X*710, new Admin Command
for loading user defined configurations is added.
PPP is a format of extend configuration for X*710, it allows user to
load user defined configuration to X*710.

List of possible use cases for extended X*710 configuration using
profiles could include following:
Configuring Analyzer/Parser to support new protocols, e.g.
- IP L2TPv3 tunneling protocol
- IPSec ESP/AH protocols
- MPLSoGRE, MPLSoUDP tunnels
- GTP-C/GTP-U tunnels
New PCTYPEs for offloading packet classification to X*710. e.g.
- new IP Protocol in addition to TCP/UDP/SCTP
- new TCP/UDP subtypes, like TCP SYN, TCP FIN
- new PCTYPE for tunneled packets like GTP-C, GTP-U
New PTYPEs for packets identification, e.g.
- MAC, MPLS, IP4, UDP
- MAC, MPLS, MPLS, IP6, TCP
Fixes for NVM configuration, e.g.
- list of enabled stat counters to improve throughput
- parser/analyzer configuration for some corner cases

v7 changes:
 Fix one coding style problem.
 Add condition during ddp processing.

v6 changes:
 Change pipeline personalization profile to dynamic device profile.

v5 changes:
 Change parameter of rte_pmd_i40e_process_ppp_package to extend operation.
 Change structure rte_pmd_i40e_profile_info.

v4 changes:
 Fix compile error with gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3).
 Move ppp related structures to rte_pmd_i40e.h.
 Not support remove PPP temporarily.

v3 changes:
 Move ppp AQ command code to base code.
