💅 mxl862xx_stats_poll ✨

okay so bestie, you know the kernel API manual mxl862xx_stats_poll(9)? we're doing a whole deep dive on it rn and honestly it's lowkey iconic 🎀

🌸 NAME 🌸

mxl862xx_stats_poll — Read RMON counters and accumulate into 64-bit stats 💖

fr fr that's the whole vibe: you read the counters, you add 'em up into 64-bit stats. no cap.

---

✨ SYNOPSIS ✨

void mxl862xx_stats_poll (struct dsa_switch *ds , int port );

literally that's it. two args, void return, she's clean 🫶

---

🦋 ARGUMENTS 🦋

• ds — the DSA switch 💅 like, the actual switch object we're working with
• port — port index 🌈 which port we're polling, bestie

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ the firmware RMON counters are free-running 32-bit values — except the byte counters, those are 64-bit, main character energy 👑

this function reads the hardware via MDIO (and yes, it may sleep, so don't be weird about it 😴), computes deltas from the previous snapshot, and accumulates them into 64-bit per-port stats — all of it under a spinlock 🌀

and here's the part where it gets cute: this is called only from the stats polling workqueue — serialized by the single-threaded delayed_work, so no MDIO locking is needed here 🙈 like, the design already handled it, we're just vibing 🌸

⚠️ quick vibe check: it may sleep (MDIO, remember?) — so respect that, bestie. and don't go calling it from random contexts. the workqueue is the whole point 💀
