💖 ice_lbtest_prepare_rings(9) — a Kernel API Manual moment 💖

okay so bestie, sit down, because we're diving into the Kernel API Manual and today's main character is ice_lbtest_prepare_rings 🧚✨ lowkey a whole vibe.

✨ NAME ✨

ice_lbtest_prepare_rings — it sets up the Tx/Rx test rings, that's literally the whole gig 🎀

🌸 SYNOPSIS 🌸

int ice_lbtest_prepare_rings (struct ice_vsi *vsi );

no cap, that's the signature, copy it exactly bestie 🫶

🦋 ARGUMENTS 🦋

  • vsi — a pointer to the VSI structure. that's the one singular thing you're handing over 💅

💜 DESCRIPTION 💜

so what this function does is configure the rings of a VSI for a loopback test — and here's the iconic part: it does it without enabling interrupts and without informing the kernel about new queues 🙈 like it's sneaking around, doing its little job, no paperwork, no drama.

it returns 0 on success, and a negative value on failure. periodt. that's it, that's the contract ⭐

🔥 SEE ALSO 🔥

the kernel file, first of all:

  • Kernel file ./drivers/net/ethernet/intel/ice/ice_ethtool.c

and now the full squad, all of them, in order, nobody gets left behind 😭👑

iykyk, that's a lot of friends and every single one of them stays in the list 💀💖

ngl bestie, this one's short and sweet — it's giving "quiet little helper function that just configures rings and dips" ✨

and that's the page!! big kiss to ./drivers/net/ethernet/intel/ice for the source and to October 2026 for the date, mwah 💋🎀 see u in the next manpage 🦋🌈
