[dpdk-dev] [PATCH v3 05/69] net/ice/base: add funcs to create new switch recipe

[Leyi Rong]

Add functions to support following admin queue commands:
1. 0x0208: allocate resource to hold a switch recipe. This is needed
when a new switch recipe needs to be created.
2. 0x0290: create a recipe with protocol header information and
other details that determine how this recipe filter work.
3. 0x0292: get details of an existing recipe.
4. 0x0291: associate a switch recipe to a profile.
