ice_set_phy_type_from_speed(9)

💖 ice_set_phy_type_from_speed(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's a function page, and yes the function is literally named ice_set_phy_type_from_speed, we love a descriptive king 👑

---

✨ NAME ✨

ice_set_phy_type_from_speed — sets phy_types based on speeds and advertised modes 🎀

like. that's the whole gig. it looks at what you're advertising and figures out which phy types match. iconic behavior, no notes 💅

---

🌸 SYNOPSIS 🌸

void ice_set_phy_type_from_speed (const struct ethtool_link_ksettings *ks , u64 *phy_type_low , u64 *phy_type_high , u16 adv_link_speed );

returns void btw — it's not gonna hand you anything back, it just does the thing and dips 🫶

---

🦋 ARGUMENTS 🦋

• ks — the ethtool link ksettings struct 🧚 this is your source of truth, the settings container itself
• phy_type_low — a pointer to the lower part of phy_type ⬇️ yes bestie she's split in two, keep up
• phy_type_high — a pointer to the higher part of phy_type ⬆️ the other half of the duo, main character energy fr fr
• adv_link_speed — the targeted link speeds bitmap 🌈 a bitmap, so think flags-in-a-big-number, iykyk

ngl the split into low/high is just how it's stored — the docs say "lower part" and "higher part," and we are not out here inventing extra lore 🔥

okay that's the page!! this one comes straight out of ./drivers/net/ethernet/intel/ice and it's dated October 2026, and yes, the header at the top and the ice_set_phy_type_from_speed(9) footer are both doing their little bookend thing 💜 thanks for reading bestie, go set some phy types, you got this 🎀✨
