fm10k_iov_configure_tc_pf(9)

💅 fm10k_iov_configure_tc_pf(9) — the Kernel API Manual glow-up ✨

okay so bestie, we're in the Kernel API Manual today and the main character is fm10k_iov_configure_tc_pf(9) — say that five times fast, i dare you 🫶 she's a little function with one job and she ate, no cap.

---

✨ SYNOPSIS ✨

here's the exact summoning spell, copy it character for character or it won't work, iykyk:

s32 fm10k_iov_configure_tc_pf (struct fm10k_hw *hw , u16 vf_idx , int
rate );

she takes three things and returns an s32 — that's the whole vibe 💫

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 🧚 your little handle on the hardware, she needs it, don't ghost her
• vf_idx — index of VF receiving GLORT 🌸 literally which virtual function is getting the GLORT
• rate — Rate indicated in Mb/s 🔥 the speed cap, measured in megabits per second

---

🦋 DESCRIPTION 🦋

so what does she do? she configures the TC for a given VF so it's only allowed up to a given number of Mb/s of outgoing Tx throughput 💅 that's it, that's the whole flex — a Lil rate limit for the traffic class, keepin' that VF from hogging the whole pipe.

lowkey important: it's outgoing Tx throughput we're capping here, bestie. not incoming. don't get it twisted 🙈
