[dpdk-dev] [PATCH v3 01/20] net/ice/base: add parser create and destroy skeleton

[Qi Zhang <qi.z.zhang@intel.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 used to feed the FXP profile creation
directly.

The patch added skeleton of the parser instance create and
destroy APIs:
ice_parser_create
ice_parser_destroy
