💅 ipc_mux_check_n_restart_tx — the Kernel API Manual one, bestie ✨

okay so real talk, this page lives in the Kernel API Manual (section 9, kernel-land, not your regular man 1 girlies) and it's about ipc_mux_check_n_restart_tx. say it with me: ipc_mux_check_n_restart_tx. iconic name, honestly.

🌸 NAME 🌸

ipc_mux_check_n_restart_tx — bestie, this one checks for pending UL date bytes and then it restarts the net interface tx queue if the device has set flow control as off.

not me pointing out that the manpage literally says "date" bytes 🙈 that's what it says, we're just reporting the news, no cap.

she returns void, she takes one pointer, she's lowkey chill like that 🫶

🎀 ARGUMENTS 🎀

• ipc_mux — a pointer to the MUX data-struct. that's the whole vibe. one arg, one job 👑
