efx_filter_is_mc_recipient(9)

📦 version 7.3.1, in nixpkgs unstable

okay so this is efx_filter_is_mc_recipient(9), fresh out of the Kernel API Manual, and honestly? It's giving tiny-but-iconic helper energy. No cap.

💖 NAME 💖

efx_filter_is_mc_recipient — test whether spec is a multicast recipient. That's the whole vibe: it checks if a spec is being a little multicast receiver or not. 🦋

✨ SYNOPSIS ✨

bool efx_filter_is_mc_recipient (const struct efx_filter_spec *spec );

🎀 ARGUMENTS 🎀

  • spec — the specification to test. That's it, bestie. One argument, zero drama. 💅

🔥 RETURN 🔥

It returns true if the specification is a non-drop RX filter that matches a local MAC address I/G bit value of 1, or matches a local IPv4 or IPv6 address value in the respective multicast address range. Otherwise? false. Periodt. 👑

ngl this is one of those return values where the details are the whole personality — don't skim it. 😭
