netif_inherit_tso_max(9)

💅 netif_inherit_tso_max — like, the whole Kernel API Manual, but make it make sense 🎀

okay so bestie, welcome to netif_inherit_tso_max(9) from the Kernel API Manual — yes, that manual, the big one. this is a tiny little function with a huge glow-up energy: it just copies TSO limits. that's it. that's the whole vibe. ✨

---

🌸 NAME 🌸

netif_inherit_tso_max — copies all the TSO limits from a lower device to an upper one. not some of them. all of them. no cap. 👑

---

🦋 SYNOPSIS 🦋

void netif_inherit_tso_max (struct net_device *to , const struct net_device *from );

like, look at that signature. immaculate. void return, so it hands you nothing back — it just does the thing and leaves. main character behaviour fr fr. 💅

---

🎀 ARGUMENTS 🎀

• to — the netdev you're updating, aka the glow-up recipient. this is the one getting the new limits. she's the upper device and she's thriving. 💖
• from — the netdev you're copying the limits from. the lower device. the source of truth. the OG. you're taking her TSO limits and gifting them to to. 🫶

✨ SEE ALSO ✨

okay so this is the part where the manpage just. keeps. going. like the SEE ALSO section said "let me introduce you to literally everyone." but respect, we're listing all of them because every single one matters. 💀

okay that's the whole page — go copy some TSO limits, you absolute icon. and remember: ./net/core, October 2026, straight out of the Kernel API Manual, netif_inherit_tso_max(9). mwah. 💜
