ksz_alloc_mem(9)

okay so bestie, welcome to ksz_alloc_mem, straight out of the Kernel API Manual, section 9 (that's the kernel-functions girlies 💅). It's a little function that does one job and does it cute.

---

✨ NAME ✨

ksz_alloc_mem — allocate memory for hardware descriptors 🎀

---

🌸 SYNOPSIS 🌸

int ksz_alloc_mem (struct dev_info *adapter );

(yes the space before the ) is canon, don't come for me 🙈)

---

🎀 ARGUMENTS 🎀

• adapter — the adapter information structure. That's it. That's the whole vibe. She just wants her adapter struct 💖

---

💅 DESCRIPTION 💅

Okay so listen. This function allocates memory — and not just any memory, memory that's specifically for the hardware descriptors used for receiving and transmitting. So like, the RX and TX descriptor situation? That's her. She's building the little descriptor homes so the hardware has somewhere to live. iconic behavior honestly 🦋

And the return? She returns 0 if it went well. That's the whole promise. Zero means slay, we're good ✅

ngl bestie, that's literally the entire documented contract — she returns 0 on success, no other return values listed. Don't go inventing drama that isn't in the text 💀

🦋 SEE ALSO 🦋

Right so this is the part where the page just dumps the entire friend group on you — the kernel file lives at ./drivers/net/ethernet/micrel/ksz884x.c and it has a lot of associated structs and functions. Like, this is the whole group chat, all of them, no cap. I'm not summarizing a single one because every last reference matters 👑
