dsa_broadcast(9)

okay bestie, welcome to the Kernel API Manual page for dsa_broadcast(9) — we're gonna make it make sense 💅✨

🌸 NAME 🌸

dsa_broadcast is the function that notifies all DSA trees in the system, no cap. 💖

✨ SYNOPSIS ✨

int dsa_broadcast (unsigned long e , void *v );

🎀 ARGUMENTS 🎀

• e — the event, and it must be of type DSA_NOTIFIER_*. ⭐
• v — the event-specific value. 🦋

🦋 DESCRIPTION 🦋

okay so you can use this to notify the switching fabric about events — think cross-chip bridging between disjoint trees. The example vibe is islands of tagger-compatible switches bridged by an incompatible middle switch. 🏝️🔗

🚨 WARNING: this function is not reliable during probe time, bestie. Why? Because probing between trees is asynchronous, and not all DSA trees might have probed yet. 😭
