Tony Nguyen says: ==================== Intel Wired LAN Driver Updates 2023-08-17 (ice) This series contains updates to ice driver only. Jan removes unused functions and refactors code to make, possible, functions static. Jake rearranges some functions to be logically grouped. Marcin removes an unnecessary call to disable VLAN stripping. Yang Yingliang utilizes list_for_each_entry() helper for a couple list traversals. Przemek removes some parameters from ice_aq_alloc_free_res() which were always the same and reworks ice_aq_wait_for_event() to reduce chance of race. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: ice: split ice_aq_wait_for_event() func into two ice: embed &ice_rq_event_info event into struct ice_aq_task ice: ice_aq_check_events: fix off-by-one check when filling buffer ice: drop two params from ice_aq_alloc_free_res() ice: use list_for_each_entry() helper ice: Remove redundant VSI configuration in eswitch setup ice: move E810T functions to before device agnostic ones ice: refactor ice_vsi_is_vlan_pruning_ena ice: refactor ice_ptp_hw to make functions static ice: refactor ice_sched to make functions static ice: Utilize assign_bit() helper ice: refactor ice_vf_lib to make functions static ice: refactor ice_lib to make functions static ice: refactor ice_ddp to make functions static ice: remove unused methods ==================== Link: https://lore.kernel.org/r/20230817212239.2601543-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
