🦋 phy_do_ioctl_running(9) 🦋

okay so bestie, welcome to the Kernel API Manual 💖 — this page is all about phy_do_ioctl_running(9). It’s giving “generic ndo_eth_ioctl implementation but test first” energy, and we’re gonna go through it together, no cap. ✨

💖 NAME 💖

phy_do_ioctl_running — generic ndo_eth_ioctl implementation but test first. 🫶

✨ SYNOPSIS ✨

int phy_do_ioctl_running (struct net_device *dev , struct ifreq *ifr ,
       int cmd );

🎀 ARGUMENTS 🎀

• dev — the net_device struct. literally the device in question, bestie.
• ifr — struct ifreq for socket ioctl’s. yep, that apostrophe is iconic.
• cmd — ioctl cmd to execute. slay.

🌸 DESCRIPTION 🌸

Same as phy_do_ioctl, but ensures that net_device is running before handling the ioctl. that’s the whole vibe: it does the same thing, but first it makes sure the net_device is running before it handles the ioctl. periodt. 💅
