i40iw_close(9)

💅 i40iw_close(9) — bestie's guide to closing an iWARP/UDA client 💅

okay so this one lives in the Kernel API Manual, section 9 (that's the kernel API section, iykyk 🧚). Sit down, grab a strawberry drink 🍓, and let's get into it.

✨ SYNOPSIS ✨

void i40iw_close (struct i40e_info *cdev_info , struct i40e_client
*client , bool reset );

literally just three args and it returns void — no return value, no drama, no notes. 👑

🎀 ARGUMENTS 🎀

• cdev_info — the parent LAN device's information structure, the one holding all the data and ops. it's giving "family tree but make it structs" 🌈
• client — the client we're closing. say bye bestie 🫶
• reset — a flag that says whether this close is happening because of a reset. yes/no energy 💀

🌸 DESCRIPTION 🌸

So the LAN driver calls this one while it's processing a client unregister. What does it actually do? It destroys stuff and cleans up the driver resources. that's it, that's the whole vibe — teardown era, no cap 🧹✨

It's a close operation, so think "packing up your room at the end of the school year" — destroy and clean up the driver resources, and don't leave anything behind. 💖
