bnx2x_mcast..._registry_e2(9)

🌸 NAME 🌸

Okay so this is page bnx2x_mcast..._registry_e2(9) from the Kernel API Manual, and the star of the show is bnx2x_mcast_refresh_registry_e2 — literally the function that recalculates the actual number of set bins. That's it, that's the whole vibe. ✨

🎀 SYNOPSIS 🎀

int bnx2x_mcast_refresh_registry_e2 (struct bnx2x *bp , struct bnx2x_mcast_obj *o );

💜 ARGUMENTS 💜

• bp — the device handle, bestie. your entry point to the whole device 🫶
• o — yeah so the manpage just... doesn't say anything here. no description. blank. nothing. not me being honest about the source material 😭 it's a struct bnx2x_mcast_obj * because the synopsis says so, and that's all we're given 💀

✨ DESCRIPTION ✨

So what this actually does is recalculate the actual number of set bins in the registry, and it does it using Brian Kernighan's algorithm — which is iconic of it, honestly. The way that algorithm works out is that its execution complexity is as a number of set bins. 👑

And what does it give you back? It returns 0 for the compliance with bnx2x_mcast_refresh_registry_e1. That's the returning contract, fr fr. 🎀
