t4_fw_reset(9)

💅 t4_fw_reset — the t4_fw_reset(9) glow-up

okay so bestie, gather round, because this one is from the Kernel API Manual and it is so much simpler than it looks. Like, genuinely. One function, three arguments, one job. Main character energy with zero drama. ✨

---

🌸 NAME 🌸

t4_fw_reset — issue a reset to FW

(that's firmware, babe, not your fav mutual. she's getting a little reboot 💅)

---

🎀 SYNOPSIS 🎀

int t4_fw_reset (struct adapter *adap , unsigned int mbox , int reset );

that's the whole blueprint, and honestly? iconic. no notes. 🫶

---

🦋 ARGUMENTS 🦋

• adap — the adapter. the whole device we're messing with. your lil networking bestie. 👑
• mbox — mailbox to use for the FW command. yes, mailbox. it's the messaging lane where FW stuff gets dropped off. 📬
• reset — specifies the type of reset to perform. like, which flavour of reset, because apparently one wasn't enough. you pick. 💀

---

🔥 DESCRIPTION 🔥

Issues a reset command of the specified type to FW.

that's it. that's the description. she does exactly what her name says, no cap. you hand her the reset type and she sends that reset command out to firmware, periodt. ✨

ngl the manpage is not long on lore here, so we're not gonna invent any — no guessing at behaviour, that's the rule. this is the entire documented vibe check. 🧚

🌈 SEE ALSO 🌈

okay this is the part where the manpage absolutely ate, because the see-also list is enormous and I refuse to leave a single one out. she references everything. obsessed. 💖

like I said. everything. she's a connector, fr fr. 🔗

💀 quick vibe check before you go: the only thing documented here is that she issues a reset command of the specified type to FW. don't go assuming extra behaviour — if it's not on this page, it's not on this page. 🙈

and that's the whole page, bestie! source/version deets for the credits: ./drivers/net/ethernet/chelsio..., dated October 2026, and we're out here reading t4_fw_reset(9) from the Kernel API Manual. slay, bye! 🎀💜🦋
