like literally that's it. that's the whole job. it adds up the per-CPU counters and hands you the total. iconic behaviour, no notes 👑

✨ SYNOPSIS ✨

u64 batadv_sum_counter (struct batadv_priv *bat_priv , size_t idx );

so you hand it a bat_priv and an idx, and it gives you back a u64. simple. clean. ate 💅

---

🎀 ARGUMENTS 🎀

• bat_priv — the bat priv with all the mesh interface information 🦋 this is the big one, the main character of the struct world, it's holding all the mesh interface tea
• idx — index of counter to sum up 🔥 like, which counter, bestie. pick one. this is the one you're adding up
