efx_siena_fi...mc_recipient(9)

okay bestie, welcome to the efx_siena_fi...mc_recipient(9) page in the Kernel API Manual 💖 this one is short, but it’s giving “tiny function, very important vibe check” energy. no cap.

✨ NAME ✨

efx_siena_filter_is_mc_recipient — test whether spec is a multicast recipient 🦋

💅 SYNOPSIS 💅

bool efx_siena_filter_is_mc_recipient (const struct efx_filter_spec
*spec );

🎀 ARGUMENTS 🎀

• spec — specification to test, bestie. that’s the thing getting the vibe check 💖

🌈 RETURN 🌈

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.

lowkey that’s the whole rule: non-drop RX filter + multicast-ish match = true; everything else = false 💅
