ixgbe_get_flash_bank_offset(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ixgbe_get_flash_bank_offset — from the Kernel API Manual, bestie ✨

okay so picture this: you're deep in the kernel docs, specifically the Kernel API Manual, and you stumble on ixgbe_get_flash_bank_offset. that's the function we're doing today. she's giving flash-bank-librarian energy and honestly? iconic. 🎀

✨ NAME ✨

ixgbe_get_flash_bank_offset — literally just "get offset into requested flash bank." that's the whole vibe. you ask for a bank, she tells you where in the flash it lives. no cap. 💖

🌸 SYNOPSIS 🌸

int ixgbe_get_flash_bank_offset (struct ixgbe_hw *hw , enum
       ixgbe_bank_select bank , u16 module );

like, that's the signature, copy it exactly, do not freestyle it, periodt. 💅

🦋 ARGUMENTS 🦋

  • hw — pointer to the HW structure. yes bestie, the hardware struct. she needs to know which hardware she's talking to 🫶
  • bank — whether to read from the active or inactive flash bank. you literally have to pick one, no "both" option, main character decision making only 👑
  • module — the module to read from. which module? the one you pass in. groundbreaking i know 😭

🌈 DESCRIPTION 🌈

so here's the tea: based on the module you hand her, she looks up the module offset from the beginning of the flash. that's it. that's the whole function. she takes your module, does the lookup, and hands you back where that module starts in the flash image. the way that this is exactly the kind of small focused function i love to see?? 🔥

⭐ RETURN ⭐

she returns the flash offset. 💖

⚠️ okay this part is important and i need you to pay attention: a value of zero is invalid and must be treated as an error. like, if you get 0 back, that is NOT "the module is at the start of flash," that is "something went wrong." do not skip this check. do not be cute about it. check it. 🙈

like, that's a whole friend group and they all showed up. obsessed. 🌸

okay that's the page bestie 💖 she's short, she's specific, and she will straight up hand you a 0 if things go wrong, so check your return values. mwah. 🫶

this lil' gem comes from ./drivers/net/ethernet/intel/i... (yes the path got cutely truncated) and it's dated October 2026 — go forth and look up those flash offsets, queen 👑✨
