ice_set_max_bw_limit(9)

💅 ice_set_max_bw_limit(9) 💅

okay so bestie, we're in the kernel API manual and this page is ice_set_max_bw_limit(9) — the intel ice driver girlies' little function for capping how fast your Tx can go. she's giving traffic-cop energy, no cap ✨

---

🌸 NAME 🌸

ice_set_max_bw_limit — setup maximum BW limit for Tx based on max_tx_rate

like literally, she takes your max_tx_rate and turns it into a bandwidth ceiling. periodt.

---

✨ SYNOPSIS ✨

int ice_set_max_bw_limit (struct ice_vsi *vsi , u64 max_tx_rate );

---

🎀 ARGUMENTS 🎀

• vsi — the VSI that's getting configured 🫶 this is the one being ✨styled✨
• max_tx_rate — the max Tx rate in Kbps that you want set as the BW limit. that's the number, in Kbps, fr fr.

---

🦋 DESCRIPTION 🦋

okay so here's the tea 🍓: if max_tx_rate comes in as 0, that's the vibe of "clear the maximum BW limit profile" — like wiping the slate clean, no cap, she's free 💀. otherwise, a non-zero value will force a maximum BW limit for the VSI on TC 0. so it's one or the other, bestie — zero means clear, not-zero means cap, and it's always TC 0. that's the whole story 🎀
