π libie_ctlq_xn_process_send β the Kernel API Manual, bestie edition π
Okay so real talk, we're deep in the Kernel API Manual today and the star of the show is libie_ctlq_xn_process_send(9). Like, the whole entire function. Pull up a chair. π«Ά
β¨ NAME β¨
libie_ctlq_xn_process_send β it processes and sends a control queue message. That's it. That's the whole arc. It's giving "one job, done correctly." π
πΈ SYNOPSIS πΈ
int libie_ctlq_xn_process_send (struct libie_ctlq_xn_send_params *params
, struct libie_ctlq_xn *xn );
Two args, one int coming back at you. Iconic signature, no notes. π
π¦ ARGUMENTS π¦
paramsβ the Xn send param information for sending a control queue message. Like, this is the little info packet that tells everything what to do. It's the main character, honestly. β¨xnβ the assigned Xn entry for tracking the control queue message. Think of it as the designated tracker. Someone's gotta keep tabs, and it'sxn. π

π SEE ALSO π
Bestie, the cross-reference list is long and we're reading all of it. Not me being thorough. Fr fr. π
- The kernel file
./drivers/net/ethernet/intel/libie/controlq.cβ yes, that's the one, the source of truth, go look at it. π

Go read them all, iykyk. πβ¨
Lowkey reminder:struct libie_ctlq_xn_rel_tx_ctx(9)is literally written withstructin front of it in the original list, so we're keeping that exactly as-is. Copying it wrong would be a crime. π¨
And that's the page, bestie!! π Written from ./drivers/net/ethernet/intel/l..., dated October 2026, and the whole thing is filed under libie_ctlq_xn_process_send(9) because that's just how we do. Mwah! ππβ
