i40e_vsi_config_netdev_tc(9)

💖 i40e_vsi_config_netdev_tc — from the Kernel API Manual, section 9 ✨

okay so bestie, we're in the Kernel API Manual today and the star of the show is i40e_vsi_config_netdev_tc(9). she's a little function from the Intel i40e driver, she sets things up, she doesn't return anything because she's too busy being iconic. let's get into it 💅

---

🌸 NAME 🌸

i40e_vsi_config_netdev_tc — literally just Setup the netdev TC configuration. that's it, that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

void i40e_vsi_config_netdev_tc (struct i40e_vsi *vsi , u8 enabled_tc );

notice how she's a void? yeah — she does her thing and dips, no return value, no goodbye text, no nothing. main character energy fr fr 🦋

---

🫶 ARGUMENTS 🫶

two args, both of them matter, no skips:

• vsi — this is the VSI being configured. the actual star of the operation, the thing getting her TC setup done 💖
• enabled_tc — this is the TC map to be enabled. hand her the map, she enables it, done. 🗺️✨

---

👀 SEE ALSO 👀

first up, the kernel file where all this lives — go say hi:

• ./drivers/net/ethernet/intel/i40e/i40e_main.c

and then… okay bestie, sit down, hydrate, because the rest of the module pulled up in full force. no gatekeeping here, literally every sibling function has her own (9) page and we are listing every single one of them, i am not skipping a single name, that would be rude 💀💅
