okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, and yes it's serving very much "I read the source so you don't have to" energy ✨. Today's main character is acpm_dequeue_by_polling, and honestly? She's the one doing the RX dequeue by polling. That's it, that's the whole vibe of the NAME section, and I'm obsessed 🎀

       acpm_xfer *xfer );
