💅 bond_advance_esn_state(9) — like, the whole glow-up, bestie

okay so this is a page straight out of the Kernel API Manual (yes, that manual, the one your kernel-dev bestie keeps open in another tab 🫶). It's a kernel function page, and no cap, it's short — but it's iconic in its own little way.

✨ NAME ✨

bond_advance_esn_state — bestie, it's the ESN support for IPSec HW offload. That's it. That's the whole vibe. ESN = Extended Sequence Numbers, HW offload = the hardware doing the heavy lifting so the CPU can chill 💅

🌸 SYNOPSIS 🌸

void bond_advance_esn_state (struct xfrm_state *xs );

literally that's the whole signature. no return value, no drama. it's giving "I do one thing and I do it well" energy. ✨

🎀 ARGUMENTS 🎀

• xs — pointer to transformer state struct. yep, that's the only thing you hand it. one argument, one job, main character energy fr fr. 🦋

and that's the whole page, diva. it lives over in ./drivers/net/bonding, dated October 2026, and it's filed under bond_advance_esn_state(9) in the Kernel API Manual — go off, kernel docs, you ate. 💖🎀🌈
