📦 version 7.3.1, in nixpkgs unstable

💅 arc_emac_get_drvinfo

okay so real talk, this is a page straight out of the Kernel API Manual (that's the manual name bestie, we're in the big-leagues section 9), and honestly? it's a lil one. but it slays at the one thing it does, and i'm gonna walk you through it 🫶

✨ NAME ✨

arc_emac_get_drvinfo — literally just: get EMAC driver information. that's it. that's the whole gig 👑

🌸 SYNOPSIS 🌸

void arc_emac_get_drvinfo (struct net_device *ndev , struct ethtool_drvinfo *info );

two pointers walk into a function and neither one of them comes back out with a return value. void queen behavior, we love a function that doesn't need to prove anything 💅

🎀 ARGUMENTS 🎀

  • ndev — pointer to a net_device structure. your network device, your main character ✨
  • info — pointer to an ethtool_drvinfo structure. this is the lil container the driver info gets poured into 🍓

🔥 DESCRIPTION 🔥

so what does it actually do? it implements the ethtool command for getting the driver information. that's the vibe check, and it passes ✅

and like… how do you even trigger this bad boy? super easy, no cap. just issue

ethtool -i ethX

at the linux prompt and boom, this function gets executed. that's it. ethtool -i on your ethX interface = this function runs. iconic, lowkey 🦋

ngl bestie, that's the whole description. short manpage, but it ate and left no crumbs 🙈

⭐ SEE ALSO ⭐

the kernel file to go peek at is ./drivers/net/ethernet/arc/emac_main.c — that's where the magic lives 🧚

and here's the whole friend group, no one left behind fr fr:

that's a wrap bestie!! this page lives at ./drivers/net/ethernet/arc, it's dated October 2026, and it's filed under arc_emac_get_drvinfo(9) — go forth, run ethtool -i ethX, and get that driver info 💖✨🎀
