🎀 octep_ctrl_net_set_mtu — setting the MTU in firmware, bestie edition 🎀

okay so this is a page from the Kernel API Manual, section 9 (kernel API, iykyk), and it's all about octep_ctrl_net_set_mtu — literally the function that sets the MTU in firmware. ✨

int octep_ctrl_net_set_mtu (struct octep_device *oct , int vfid , int
mtu , bool wait_for_response );

---

🦋 ARGUMENTS 🦋

• oct — a non-null pointer to struct octep_device. Non-null, bestie, we're not playing games here. 👑
• vfid — Index of virtual function.
• mtu — mtu. that's it. that's the whole description. iconic minimalism tbh 🎀
• wait_for_response — poll for response. 🫶
