ice_ethtool_get_maxspeed(9)

🌸 NAME 🌸

okay so bestie, welcome to ice_ethtool_get_maxspeed(9) — the Kernel API Manual page that is literally here to get the max speed for given lport. That's the whole vibe. No cap. 💅

---

✨ SYNOPSIS ✨

Here's the exact signature — do not touch the spacing, bestie, it's giving very specific:

int ice_ethtool_get_maxspeed (struct ice_hw *hw , u8 lport , u8
*max_speed );

---

🎀 ARGUMENTS 🎀

okay the cast is:

• hw — pointer to the HW struct. main character pointer energy ✨
• lport — logical port for which max speed is requested. this is the port, bestie 🫶
• max_speed — return max speed for input lport. this is where the answer goes 💖

---

🔥 RETURN 🔥

• 0 on success
• negative on failure

0 = slay, negative = not slay 😭 that's the whole return vibe.
