i40e_netif_...tx_rx_queues(9)

📦 version 7.3.1, in nixpkgs unstable

💖 i40e_netif_set_realnum_tx_rx_queues 💖

okay so bestie, welcome to the Kernel API Manual — yes we're reading i40e_netif_...tx_rx_queues(9) together, section 9, and it's giving very much "one tiny function, one giant SEE ALSO list" energy. Sit down, hydrate, let's go 🫶

✨ NAME ✨

i40e_netif_set_realnum_tx_rx_queues — update the number of tx/rx queues 💅

🎀 SYNOPSIS 🎀

int i40e_netif_set_realnum_tx_rx_queues (struct i40e_vsi *vsi );

literally one argument, one int back, no cap 🧚

🌸 ARGUMENTS 🌸

  • vsi — the vsi structure. that's it. that's the whole argument. it's the VSI bestie in question, and yes the manual page just says "vsi structure" so I'm not gonna invent lore about it 🔥

🦋 DESCRIPTION 🦋

so what does she do? this function updates netdev's number of tx/rx queues. that's the whole vibe — you've got a netdev, it's got a queue count, and this is the glow-up that makes the count match reality ✨

and then — because she's an overachiever — she returns the status of setting tx/rx queues. so like, you get a status back. pay attention to it, king 👑
