Subject: [PATCH net-next v2 01/13] ice: add parser create and destroy skeleton

From: Junfeng Guo <junfeng.guo@...el.com>

Add new parser module which can parse a packet in binary and generate
information like ptype, protocol/offset pairs and flags which can be later
used to feed the FXP profile creation directly.

Add skeleton of the create and destroy APIs:
ice_parser_create()
ice_parser_destroy()
