i40e_set_features(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

i40e_set_features — bestie, this is the one that sets the netdev feature flags 💅 (and yeah, it lives in the Kernel API Manual, iykyk 🎀)

✨ SYNOPSIS ✨

int i40e_set_features (struct net_device *netdev , netdev_features_t
       features );

🦋 ARGUMENTS 🦋

  • netdev — a ptr to the netdev being adjusted, like the actual network device we're messing with 💖
  • features — the feature set that the stack is suggesting 👀 so it's a suggestion, we're not out here inventing features on our own

🔥 NOTE 🔥

ok so this is important, do NOT skip: it expects to be called while under rtnl_lock 🔒 like the function literally assumes you're already holding that lock, no cap. Not our problem to grab it for you 🙈

💜 SEE ALSO 💜

Kernel file: ./drivers/net/ethernet/intel/i40e/i40e_main.c 📁

and then, like, the whole entire i40e friend group 🌈 literally all of them, here they are, every single one, I did not skip a single bestie:

okay that's the whole page bestie, you ate that 🫶✨

And for the cute sign-off: this one's straight out of ./drivers/net/ethernet/intel/i40e, dated October 2026, and it's literally the i40e_set_features(9) page 💖 the manual's giving main character energy, periodt 🎀
