bnx2x_nvram_read(9)

👑 bnx2x_nvram_read — from the Kernel API Manual, bestie 💅

okay so, real talk: this is the man page for bnx2x_nvram_read, straight out of the Kernel API Manual (section 9, kernel functions, iykyk). It's a tiny little function with one job and honestly it ate. Let's get into it 🫶

---

✨ NAME ✨

bnx2x_nvram_read — reads data from nvram [might sleep]

yep, that's the whole vibe. it reads stuff out of nvram. and the [might sleep] in brackets? not a drill, not me being dramatic — that's literally in the name, so don't go calling this in a context where snoozing is forbidden 😴💀

---

🌸 SYNOPSIS 🌸

int bnx2x_nvram_read (struct bnx2x *bp , u32 offset , u8 *ret_buf , int
buf_size );

four args, returns an int. cute, compact, does exactly what it says on the tin ✨

---

🎀 ARGUMENTS 🎀

• bp — the driver handle. your main character struct pointer, your golden ticket, your i know a guy 🫶
• offset — byte offset in nvram. like where in the vault you're digging, measured in bytes obviously 🧚
• ret_buf — pointer to buffer where data is to be stored. this is the little basket you're carrying the data home in, so pls make sure it's real 🌸
• buf_size — Length of ret_buf in bytes. yes the capital L is theirs, yes it's iconic, and yes it's literally just telling you how big your basket is 🎀

💖 friendly reminder from your girl: the name says [might sleep]. that's not me being cutesy, that's a real caveat. don't be the person who calls this somewhere sleeping is illegal. it's giving "read the room" energy fr fr 🙈

alright that's the whole page, no cap 🌈 and for the cute sign-off: this lovely thing comes from the kernel tree path that starts ./drivers/net/ethernet/broadco... (they truncated it, not me 😭), dated October 2026, and it's the bnx2x_nvram_read(9) page itself. slay, go read your nvram responsibly 🎀✨🦋
