devlink_dpi...nter_enabled(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to the Kernel API Manual — yes, that's the whole vibe, a kernel API manual, and honestly? it ate. sit down, hydrate, let's talk about counters ✨

🌸 NAME 🌸

devlink_dpipe_table_counter_enabled — check if counter allocation required 🔥

like, the function's whole job is answering one question: "do we need counters here or nah?" and it's giving very much helpful bestie energy 💅

🦋 SYNOPSIS 🦋

bool devlink_dpipe_table_counter_enabled (struct devlink *devlink , const char *table_name );

so it returns a bool, it takes a struct devlink *devlink and a const char *table_name, and no cap, that's the whole signature 🎀

🎀 ARGUMENTS 🎀

  • devlink — a devlink. yeah that's it, that's the description 😭 it's literally "devlink", the manpage said so, and we respect the manpage.
  • table_name — the table's name 💫 (the original says "tables name", which is giving slightly unhinged grammar, but the meaning is right there — it's the name of the table bestie)

✨ DESCRIPTION ✨

so here's the deal, babes 👑

This is used by the driver to check if counter allocation is required. that's the whole check. no gatekeeping 🫶

After counter allocation is turned on, the table entries are updated to include counter statistics. so like, boom 💥 suddenly your entries are out here carrying stats, main character energy fr fr 📊

After that point on, the driver must respect the counter state so that each entry added to the table is added with a counter. notice the "must" — that's not a suggestion, that's a periodt. the driver has to keep the counter state in mind for every single entry it adds, no exceptions, no "oops I forgot" 🙈

ngl this is the important bit: once counters are on, every new entry gets added with a counter. the driver has to stay in sync with that state. lowkey iconic of the kernel to just tell you directly 💅

🌈 SEE ALSO 🌈

all of these are also in ./net/devlink if you wanna go read them, and honestly you should, iykyk 🦋✨

kay that's the whole page bestie, go forth and allocate counters responsibly 💜

sign-off era: this one lives in ./net/devlink, dated October 2026 🌸 till next time, mwah 💋🎀
