i40e_get_real_pf_qid(9)
π i40e_get_real_pf_qid β the kernel API manual, bestie edition β¨
okay so this is a page from the Kernel API Manual, and the star of the show is i40e_get_real_pf_qid β a little function in the i40e driver that you're about to be obsessed with. sit down, grab a strawberry drink π, and let's get into it.
β¨ NAME β¨
i40e_get_real_pf_qid β and ngl the original literally gives you no description here π like the NAME section is out here with zero vibes, no tagline, nothing. it's giving mysterious main character energy and honestly? respect. π
π¦ SYNOPSIS π¦
here's the whole signature, character for character, no cap:
u16 i40e_get_real_pf_qid (struct i40e_vf *vf , u16 vsi_id , u16 queue_id
);
so it returns a u16, and it takes three things. that's it. that's the whole vibe check. πΈ
π ARGUMENTS π
three besties walk into the function:
vfβ pointer to the VF info. she's astruct i40e_vfpointer, she holds the whole story of the virtual function. π«Άvsi_idβ the vsi id. that's the id. of the vsi. iconic, no notes. βqueue_idβ the queue number, aka the little number that tells you which queue we're talking about. π₯
π DESCRIPTION π
so what does she do? she's a wrapper function whose whole job is to get the pf_queue_id β and the way she does it, she's handling ADq code as well πβ¨
like, that's the flex. she wraps the lookup so the ADq situation is also taken care of. periodt. π

likeβ¦ she really said "here's the entire friend group" and honestly we love a function who links her whole circle ππ¦
quick reminder bestie: everything above is straight from the page β no invented behaviour, no extra tips, just the facts in a cuter outfit. π
and that's the whole page! it lives under ./drivers/net/ethernet/intel/i40e, dated October 2026, in the Kernel API Manual β mwah, go read i40e_vc_get_pf_queue_id(9) next, she's right there in the SEE ALSO πβ¨πΈ
