💅 DPNI_CONG_OPT_FLOW_CONTROL 💅

okay bestie, welcome to the Kernel API Manual ✨ — this one's a tiny little page but it's iconic and you're gonna get it in like ten seconds, fr fr 🫶

🌸 NAME 🌸

DPNI_CONG_OPT_FLOW_CONTROL — the way that this congestion will trigger flow control or priority flow control 🔥 lowkey it's a whole vibe.

vibe check tho: this only has effect if flow control is enabled with dpni_set_link_cfg(). no cap. if you didn't do that part, this option is just standing there being decorative 💀

✨ SYNOPSIS ✨

DPNI_CONG_OPT_FLOW_CONTROL

that's it. that's the whole synopsis. main character energy, honestly 👑
