💅 rhine_set_cam_mask(9) ✨

okay so real talk, this is a page from the Kernel API Manual, section 9, and it's honestly such a tiny little icon. bestie, it's one function, it does one vibe, and it does it flawlessly. no cap.

🌸 NAME 🌸

rhine_set_cam_mask — set multicast CAM mask 🎀

---

🦋 SYNOPSIS 🦋

void rhine_set_cam_mask (void __iomem *ioaddr , u32 mask );

like… that's it. that's the whole signature. she's void, she returns nothing, she simply is. periodt. 💅

---

🍓 ARGUMENTS 🍓

• ioaddr — the register block of this Rhine. yup, that's this Rhine, the one you're holding. it's a void __iomem *, so it's giving "memory-mapped, don't touch it with your bare hands" energy. 🙈
• mask — the multicast CAM mask. it's a u32. it's the actual mask. the main character of the whole operation, honestly. 👑

---

💖 DESCRIPTION 💖

so here's the tea: mask sets the multicast filters active/inactive. that's it. that's the whole function. no extra steps, no side quests. 🧚

the mask goes in, the multicast filters get their vibe check, and they come out either active or inactive depending on what you handed over. lowkey elegant. highkey iconic. 🔥

no return value, because a void function doesn't owe you closure. she just does the thing and leaves. 🫶
