Subject: [PATCH iwl-next v3 0/7] Switch API optimizations

Optimize the process of creating a recipe in the switch block by removing
duplicate switch ID words and changing how result indexes are fitted into
recipes. In many cases this can decrease the number of recipes required to
add a certain set of rules, potentially allowing a more varied set of rules
to be created. Total rule count will also increase, since less words will
be left unused/wasted. There are only 64 rules available in total, so every
one counts.

After this modification, many fields and some structs became unused or were
simplified, resulting in overall simpler implementation.

Marcin Szycik (4):
  ice: Remove unused struct ice_prot_lkup_ext members
  ice: Optimize switch recipe creation
  ice: Remove unused members from switch API
  ice: Add tracepoint for adding and removing switch rules

Michal Swiatkowski (3):
  ice: Remove reading all recipes before adding a new one
  ice: Simplify bitmap setting in adding recipe
  ice: remove unused recipe bookkeeping data
