ntmp_fdbt_u...vity_element(9)

💅 NAME 💅

okay so bestie, gather round — ntmp_fdbt_update_activity_element is the function that updates the activity element of all the dynamic entries in the FDB table. that's it, that's the whole vibe ✨

(this one's from the Kernel API Manual, iykyk 🎀)

---

✨ SYNOPSIS ✨

int ntmp_fdbt_update_activity_element (struct ntmp_user *user );

literally just one argument, we love a low-maintenance icon 👑

---

🫶 ARGUMENTS 🫶

• user — the target ntmp_user struct. that's who we're working with, no cap 💖

---

🌸 DESCRIPTION 🌸

okay so here's the tea ☕ — one single activity update management can be used to process all the dynamic entries in the FDB table at once. efficiency queen behavior, honestly 🧚

here's how the hardware does its thing 🦋 when hardware processes an activity update management command for an entry in the FDB table, and that entry does not have its activity flag set, then the activity counter gets incremented. but!! if the activity flag is set, then both the activity flag and the activity counter get reset. two-for-one reset, iconic 💅

so software can issue those activity update management commands at predefined times, and then the value of the activity counter can be used to estimate the period of how long an FDB entry has been inactive. it's giving detective work 🔥 tracking who's been ghosting the table, fr fr 👻

⭐ RETURN ⭐

• 0 on success 🎉

ngl this page came straight out of ./drivers/net/ethernet/freesca... and it's dated October 2026 — and yes, the page title is still ntmp_fdbt_u...vity_element(9) because sometimes the terminal just truncates your name and you gotta live with it 😭💀

mwah, stay hydrated and read your error codes 💖🌈⭐
