icssg_hsr_fdb_update(9)

🎀 NAME 🎀

okay so bestie, this is the icssg_hsr_fdb_update(9) page from the Kernel API Manual — and it's literally the function that updates the FDB and VLAN table for HSR multicast. 💖

✨ SYNOPSIS ✨

void icssg_hsr_fdb_update (struct prueth_emac *emac , const u8 *addr ,
       u8 vid , u8 port_membership , bool add );

🌸 ARGUMENTS 🌸

• emac — the PRUETH EMAC private data. Like, the private stash for this EMAC. 🫶
• addr — the multicast MAC address. That's the address in question, no cap.
• vid — the VLAN ID.
• port_membership — the port membership bitmap (P0=0x1, P1=0x2, P2=0x4). So P0 is 0x1, P1 is 0x2, P2 is 0x4 — iconic bitmask behavior. ✨
• add — true to add the entry, false to delete it. Simple as that, periodt.

💅 DESCRIPTION 💅

Updates both FDB and VLAN table entries for the given address. Both tables, one address — she's doing the absolute most in the best way. 💅
