ixgbe_ipsec_restore(9)

💖 ixgbe_ipsec_restore — a Kernel API Manual moment 💖

okay bestie, so we're in the Kernel API Manual and today's main character is ixgbe_ipsec_restore(9). she's niche, she's hardware-coded, and honestly? she ate. let's get into it 🎀

---

✨ NAME ✨

ixgbe_ipsec_restore — literally just restoring the ipsec HW settings after a reset. that's the whole gig. no cap. 🦋

---

🌸 SYNOPSIS 🌸

void ixgbe_ipsec_restore (struct ixgbe_adapter *adapter );

that's it. one function, one argument, zero drama (mostly). 💅

---

🫶 ARGUMENTS 🫶

• adapter — the board private structure. she's the whole personality of the board tbh, everything lives in here. 👑

---

🔥 DESCRIPTION 🔥

so picture this: the HW tables just got bashed by a chip reset 😭 like genuinely wrecked. this function's whole job is to reload the HW tables from the SW tables after all that chaos. think of it as the glow-up after the crisis. ✨

and here's the tea about VF entries: any VF entries get removed from the SW and HW tables, because:

1. either (a) the VF also gets reset on PF reset and will ask again for the offloads — so like, she'll be back, no need to keep her seat warm 💀
2. or (b) the VF has been removed by a change in the num_vfs — in which case, gone gone, she's not coming to the function. 🙈

either way, the entries are cleared out. lowkey efficient, highkey clean. 🧚
