igb_init_mas(9)

🌸 NAME 🌸

igb_init_mas — init Media Autosense feature if enabled in the NVM 💖

okay so real quick, this is page igb_init_mas(9) from the Kernel API Manual, and honestly? she's a little one-job icon. her whole thing is setting up the Media Autosense feature — but ONLY if it's enabled in the NVM, bestie. no NVM flag, no party. that's the whole vibe check. ✨

🌈 SYNOPSIS 🌈

void igb_init_mas (struct igb_adapter *adapter );

returns nothing (void), takes exactly one thing, and that thing is an adapter. slay, minimal. 🎀

---

🦋 ARGUMENTS 🦋

• adapter — the adapter struct 🫶 like, that's it, that's the argument. hand her your adapter and she does her little NVM-checking moment.

ngl bestie, that's the whole page. one function, one argument, and a SEE ALSO list longer than my screen time report 😭 but every single one of them is up there, fr fr. 💅

okay that's a wrap!! this lil page came from ./drivers/net/ethernet/intel/igb and it's dated October 2026 — so like, go forth and autosense those media (only if the NVM says so). mwah 🫶💖✨
