okay so real talk, we're in the Kernel API Manual today and the star of the show is llc_conn_ev_qlfy_last_frame_eq_1(9) (yes the header up there truncates it to llc_conn_ev_...t_frame_eq_1(9), that's just the vibe, the real name is the long one 🫶). come sit with me.

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — this function determines when a frame that's being sent is, in fact, the last frame of the transmit window. main character energy fr fr 👑

if it is the last one, this function returns zero. else it returns one. that's it, that's the whole personality 😭

and why do we care? because this is the function used for sending the last frame of the transmit window as an I-format command with the p-bit set to one. periodt. 🔥

so to say it again, in case you scrolled past: returns 0 if frame is last frame, 1 otherwise. no cap. ⭐
