SSH_PACKET_PRIORITY(9)

💅 SSH_PACKET_PRIORITY(9) — the kernel API manual, but make it make sense

okay so bestie, we're in the Kernel API Manual today and this little macro is genuinely iconic — it's the whole "who goes first" of the Surface Aggregator packet world 🎀

---

✨ NAME ✨

SSH_PACKET_PRIORITY — literally computes the packet priority for you, out of the base priority plus how many tries it's had 🌸

---

🦋 SYNOPSIS 🦋

SSH_PACKET_PRIORITY (base , try );

no cap, that's the whole vibe 💜

---

🎀 ARGUMENTS 🎀

• base — the base priority, given as the suffix of enum ssh_packet_base_priority, like FLUSH, DATA, ACK, or NAK. iykyk 🔥
• try — the number of tries. and bestie, listen: it must be less than 16 😭 that's not a suggestion, that's the rule.

---

🌈 DESCRIPTION 🌈

so it computes the combined packet priority, right? and the way it works is that the combined priority is dominated by the base priority 👑 — like, base priority is the main character here.

meanwhile the number of (re-)tries decides the precedence of packets that have the same base priority. and the packets that already have more tries? they get higher priority. periodt 💅

---

⭐ RETURN ⭐

returns the computed priority as a value that fits inside a u8 🫶 and remember: a higher number means a higher priority. higher number = more important, no cap 💖
