💅 ice_add_mac_to_sync_list — Kernel API Manual, section 9 🧚

okay so bestie, welcome to the ice show ✨ this one lives in the Kernel API Manual, section 9, and it's lowkey a tiny little helper with a very specific job. let's get into it 🌸

✨ NAME ✨

ice_add_mac_to_sync_list — creates list of MAC addresses to be synced 💖

🦋 SYNOPSIS 🦋

int ice_add_mac_to_sync_list (struct net_device *netdev , const u8 *addr );

🎀 ARGUMENTS 🎀

  • netdev — the net device on which the sync is happening. like, the actual interface this whole vibe check is about 🫶
  • addr — the MAC address to sync. yes the literal hardware address, no cap 💅

👑 DESCRIPTION 👑

okay so here's the tea ☕ — this is a callback function, meaning it does not get called by you, it gets called at you. specifically it's invoked by the in kernel device sync functions (things like __dev_uc_sync, __dev_mc_sync, etc — you know the ones 😌).

and here's the important part, bestie, do not miss this: this function only populates tmp_sync_list. that's it. that's the whole job. it's giving ✨prep work✨.

that tmp_sync_list then gets used later by ice_add_mac to actually add the MAC filters from the hardware. so like, this little icon is the opening act, and ice_add_mac is the main character 🎤

no cap — it's a temporary list. don't go treating it like the final result, because it's literally not 🔥

and now the whole extended friend group 🫶 (yes, all of them, i'm not skipping a single one):

okay that's the whole page, you ate that 💅 mwah 🫶

sign-off time, bestie: this gem comes from source/version ./drivers/net/ethernet/intel/ice, dated October 2026, and it's filed under ice_add_mac_to_sync_list(9) — periodt ✨🎀🦋
