✨ NAME ✨

ixgbevf_ipsec_find_empty_idx — find the first unused security parameter index 🎀

like, it literally goes looking for the first free spot. that's the whole vibe check.

---

🌸 SYNOPSIS 🌸

int ixgbevf_ipsec_find_empty_idx (struct ixgbevf_ipsec *ipsec , bool
rxtable );

one function, two args, zero drama. no cap. ✨

---

🦋 ARGUMENTS 🦋

• ipsec — pointer to IPsec struct 💖 that's your main character right there, the whole struct you're poking around in.
• rxtable — true if we need to look in the Rx table 👀 like, are we checking the receive side? set this to true and we're going Rx-shopping. otherwise it's Tx time.

---

🌈 DESCRIPTION 🌈

Returns the first unused index in either the Rx or Tx SA table 🔥

that's it. that's the function. it hands you back the first index that nobody's claimed yet, in whichever of the two tables you asked about (Rx or Tx, per that rxtable bool from up top). iconic behavior honestly 💅
