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.

Actually I have no released doc to share, the documents in my hand are draft and can't be forwarded.

List of possible use cases for extended X*710 configuration using profiles could include following:
Configuring Analyzer/Parser to support new protocols, for example:
*	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. For example:
*	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, for example:
*	MAC, MPLS, IP4, UDP
*	MAC, MPLS, MPLS, IP6, TCP
Fixes for NVM configuration, for example:
*	list of enabled stat counters to improve throughput
*	parser/analyzer configuration for some corner cases

Yes, will update in next version.
