STRUCT NFP_ALINK_STATS(9)

💅 struct nfp_alink_stats(9) — from the Kernel API Manual, bestie ✨

Okay so picture this: you're deep in the kernel sources, this is the Kernel API Manual, and there's a lil struct called struct nfp_alink_stats and it's literally the whole vibe of ABM NIC statistics. That's it. That's the NAME section. 🎀

---

✨ SYNOPSIS ✨

Here's the shape of it, no cap, don't touch the semicolons:

struct nfp_alink_stats {
    u64 tx_pkts;
    u64 tx_bytes;
    u64 backlog_pkts;
    u64 backlog_bytes;
    u64 overlimits;
    u64 drops;
 };

Six u64 fields, all lined up, all iconic. 👑

🦋 Members 🦋

Okay so here's the member-by-member vibe check, one at a time, no skipping:

• tx_pkts — the number of TXed packets. Just counting the packets that got sent out. Slay. 💌
• tx_bytes — the number of TXed bytes. Same energy as above but in bytes, because bytes matter too. 🌸
• backlog_pkts — the momentary backlog length, measured in packets. Key word: momentary. It's a snapshot, not a lifetime total. 🫶
• backlog_bytes — the momentary backlog length again, but in bytes this time. Same deal, same "momentary". 💜
• overlimits — the number of ECN marked TXed packets, and this one is accumulative. Not momentary. Accumulative. Important distinction, bestie. 🔥
• drops — the number of tail-dropped packets, also accumulative. Yes, packets really said "tail drop" and left. 😭

Not me stressing the difference between "momentary" and "accumulative" — but fr fr, backlog_pkts and backlog_bytes are momentary, and overlimits and drops are accumulative. Keep that straight and you're golden. 💅

• struct nfp_abm(9)
• struct nfp_alink_xstats(9)
• struct nfp_qdisc(9)

Like, all of them. Together. A whole little friend group of structs. 🌈⭐
