ENUM DPNI_CONGESTION_POINT(9)

🌸 NAME 🌸

Okay so bestie, welcome to the enum dpni_congestion_point(9) page from the Kernel API Manual. This is literally enum dpni_congestion_point — Structure representing congestion point — and it’s lowkey iconic for such a small enum. 💅

✨ SYNOPSIS ✨

No cap, here’s the whole shape of it. Code is copied exactly, because we do not mess with the sacred characters:

enum dpni_congestion_point {
    DPNI_CP_QUEUE ,
    DPNI_CP_GROUP

};

🎀 Constants 🎀

The constants are giving “two options, both important.” Here’s the vibe check:

• DPNI_CP_QUEUE — Set taildrop per queue, identified by QUEUE_TYPE, TC and QUEUE_INDEX. Periodt.
• DPNI_CP_GROUP — Set taildrop per queue group. Depending on options used to define the DPNI this can be either per TC (default) or per interface (DPNI_OPT_SHARED_CONGESTION set at DPNI create). QUEUE_INDEX is ignored if this type is used. Slay, but also read that caveat, bestie.
