four args, all of them lowkey important, let's get into it:

  • qp — hw qp ptr 🫶 the hardware queue-pair pointer, aka the whole vibe she's operating on
  • wr_id — work request id 💫 your little name tag for this work request so you can tell it apart later
  • signaled — signaled for completion 🔥 set this to say you want that completion signal, iykyk
  • post_sq — ring doorbell 👑 yes queen, ring it — this is the bit where the doorbell actually gets rung
