wwan_port_txoff(9)

🌸 NAME 🌸

okay so bestie, welcome to wwan_port_txoff(9) from the Kernel API Manual — this one is literally Stop TX on WWAN port. 💅✨

🦋 SYNOPSIS 🦋

void wwan_port_txoff (struct wwan_port *port );

💖 ARGUMENTS 💖

• port — the WWAN port for which TX must be stopped. no cap, that's the whole argument. 🎀

✨ DESCRIPTION ✨

okay so this function is for TX flow control. A port driver calls this function to indicate that TX is temporarily unavailable — like, for example, because of ring buffer fullness. 🫶

it's giving “hold up, TX is not available right now” energy. temporary. not forever. periodt. 💅
