e1000_mng_host_if_write(9)

💅 e1000_mng_host_if_write — like, the Kernel API Manual, bestie 💖

okay so welcome to the Kernel API Manual, the part of the kernel docs where we talk about writing to the manageability host interface. yes that's a lot of words, i know, stay with me 🫶

---

✨ NAME ✨

e1000_mng_host_if_write — write to the manageability host interface. that's it, that's the whole vibe 💅

---

🌸 SYNOPSIS 🌸

s32 e1000_mng_host_if_write (struct e1000_hw *hw , u8 *buffer , u16
length , u16 offset , u8 *sum );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. the hardware herself 👑
• buffer — pointer to the host interface buffer. this is the thing we're writing ✨
• length — size of the buffer. how much of it we care about, no cap
• offset — location in the buffer to write to. iykyk, it's where you start 🦋
• sum — sum of the data. not a checksum, bestie, literally just the sum. don't get it twisted 💀

---

🧚 DESCRIPTION 🧚

so this function writes the buffer content at the offset given on the host if. like, that's the whole main character energy of it. 🎀

it also does alignment considerations to do the writes in the most efficient way — the way that it aligns things, obsessed. she's not just writing, she's writing smart 🌈

and it also fills up the sum of the buffer in *buffer parameter. yes it says *buffer. that's the manpage's words, not mine 🙈
