Miller" <davem@...emloft.net>, Jakub Kicinski <kuba@...nel.org>, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH v2 net-next 0/4] ice: switch: debloat packet templates code This hunts down several places around packet templates/dummies for switch rules which are either repetitive, fragile or just not really readable code. It's a common need to add new packet templates and to review such changes as well, try to simplify both with the help of a pair macros and aliases. bloat-o-meter is happy about that (built w/ LLVM 13): add/remove: 0/1 grow/shrink: 2/0 up/down: 148/-202 (-54) Function old new delta ice_add_adv_rule 2383 2529 +146 ice_fill_adv_dummy_packet 289 291 +2 ice_adv_add_update_vsi_list 202 - -202 Total: Before=395813, After=395759, chg -0.01% Diffstat also looks nice, and adding new packet templates now takes less lines. We'll probably come out with dynamic template crafting in a while, but for now let's improve what we have currently. Note: this will conflict with [1] going through net-next, a followup will be sent once accepted. >From v1 ([0]): - rebase on top of the latest next-queue (to fix #3 not applying); - adjust the kdoc accordingly to the function proto changes in #3; - no functional changes.
