so this function? it's used to add or remove multicast MAC addresses for the PF. that's it, that's the tea 💖 lowkey does exactly what it says on the tin — hand it a MAC and a VLAN ID and tell it add, and it's either letting that multicast address into the table or kicking it out. main character energy, honestly.
