reuse_tx_pools(9)

💖 reuse_tx_pools(9) 💖

okay so bestie, welcome to the Kernel API Manual corner of the group chat — today's main character is reuse_tx_pools, and honestly? she's a little vibe-check function for your ibmvnic adapter 🦋

---

✨ NAME ✨

reuse_tx_pools — Check if the existing tx pools can be reused. 🎀

---

🌸 SYNOPSIS 🌸

bool reuse_tx_pools (struct ibmvnic_adapter *adapter );

---

🎀 ARGUMENTS 🎀

• adapter — ibmvnic adapter 💅 that's the one and only thing she takes, no cap

---

💫 DESCRIPTION 💫

So like, this function checks if the existing tx pools in the adapter can be reused. That's literally it, she's a vibe check for pools 🔥

And when can they be reused? When the pool parameters haven't changed — and the pool parameters in question are:

• the number of pools
• the number of buffers in the pool
• and mtu

If all three are unchanged, the pools get the green light to be reused, periodt ✨

---

🙈 NOTE 🙈

okay so real talk, this assumes that all pools have the same number of buffers, which is the case currently. If that changes, we must fix this. 🫶 like, noted, bestie, no cap

---

⭐ RETURN ⭐

• true if the tx pools can be reused 💖
• false otherwise 😭
