💖 NAME 💖

okay bestie, we're in the Kernel API Manual and this is the qman_update_cgr_safe(9) page. Name check: qman_update_cgr_safe — Modifies a congestion group object from any CPU. periodt.

✨ SYNOPSIS ✨

The signature, untouched and iconic:

int qman_update_cgr_safe (struct qman_cgr *cgr , struct qm_mcc_initcgr
*opts );

🎀 ARGUMENTS 🎀

• cgr — the 'cgr' object to modify. yes, that one.
• opts — state of the CGR settings. the settings state, got it.

🌸 DESCRIPTION 🌸

okay so the whole move is: this will select the proper CPU and modify the CGR settings. That's the description, and honestly? clean, simple, slay. The way it just selects the proper CPU and modifies the CGR settings is giving exactly what it needs to give. No extra lore, no cap.
