Subject: [PATCH iwl-next v9 01/15] ice: add parser create and destroy skeleton
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 create and destroy APIs:
ice_parser_create
ice_parser_destroy
Signed-off-by: Junfeng Guo <junfeng.guo@...el.com>
