init_tx_pools(9)

💅 init_tx_pools(9) — like, the kernel API manual bestie 🎀

okay so this is init_tx_pools from the Kernel API Manual, and honestly? she's a whole vibe. let's get into it 🦋

---

✨ NAME ✨

init_tx_pools — Initialize the set of transmit pools in the adapter. ✨

🌸 SYNOPSIS 🌸

int init_tx_pools (struct net_device *netdev );

🎀 ARGUMENTS 🎀

• netdev — the net device associated with the vnic interface. that's her whole identity fr 💅

🦋 DESCRIPTION 🦋

okay so picture this: you gotta initialize the set of transmit pools in the ibmvnic adapter that's associated with the net_device netdev. that's the assignment. 🔥

and like — if possible, just reuse the existing tx pools. why do extra work when you don't have to, right? queen behavior. 👑

but if you can't reuse them? then it's giving spring cleaning: free any existing pools and allocate a new set of pools before initializing them. out with the old, in with the new, periodt. 💀✨

💖 RETURN 💖

• 0 on success 🫶
• a negative value on error 😭

ngl bestie, check that return value. a negative number is NOT the slay you think it is.
