ethtool_mmsv_init(9)

💖 ethtool_mmsv_init(9) 💖

ok so this is a page from the Kernel API Manual, bestie — it's ethtool_mmsv_init(9) and it's literally the setup girlie for the MAC Merge Software Verification state machine ✨ no cap.

---

🌸 NAME 🌸

ethtool_mmsv_init — get that MAC Merge Software Verification state all initialized and ready to slay 💅

---

🦋 SYNOPSIS 🦋

void ethtool_mmsv_init (struct ethtool_mmsv *mmsv , struct net_device
*dev , const struct ethtool_mmsv_ops *ops );

like, three args, one void return, that's the whole vibe 🎀

---

🎀 ARGUMENTS 🎀

• mmsv — the MAC Merge Software Verification state itself 💖 this is the main character
• dev — pointer to the network interface, iykyk 🌈
• ops — the methods for implementing the generic functionality — the little toolkit of how-to's 🫶

---

⭐ DESCRIPTION ⭐

okay so listen 👑 — the MAC Merge Software Verification is a timer- and event-based state machine, and it exists for network interfaces that don't have a hardware-based TX verification process (as per IEEE 802.3 clause 99.4.3, periodt). So if your NIC is out here lacking the hardware glow-up, this lil state machine steps in 🧚

who manages what, you ask? the timer is managed by the core code (not you, bestie, it's handled 💅), whereas the events are supplied by the driver — and only by the driver explicitly calling one of the other API functions. so like, no events magically appear, the driver has to actually show up and call something 🔥

ok that's the whole page, no gatekeeping 🙈 remember: core code handles the timer, driver handles the events, and mmsv is the state that gets initialized. that's it, that's the tea ☕

mwah 💋 go forth and initialize — this cutie dropped from ./net/ethtool in October 2026, brought to you by the Kernel API Manual gang 💖✨🎀🦋
