🦋✨ igb_set_uta — Set unicast filter table address ✨🦋

okay so bestie, welcome to the igb_set_uta(9) page from the Kernel API Manual 💖 pull up a chair, this one's a little hardware-flavored but we got it.

🌸 NAME 🌸

igb_set_uta — Set unicast filter table address. that's the whole vibe. it sets the unicast filter table address, no cap 💅

🎀 SYNOPSIS 🎀

void igb_set_uta (struct igb_adapter *adapter , bool set );

like, that's literally the whole signature. iconic. short. slay.

🫶 ARGUMENTS 🫶

  • adapter — your board private structure 💖 this is the main character, the struct that holds all the board's private business.
  • set — a bool telling us whether we're setting or clearing bits ✨ that's it, that's the whole job. setting = yes bestie, clearing = no bestie.

🔥 DESCRIPTION 🔥

okay so. the unicast table address is a register array of 32-bit registers 👑

the table is meant to be used in a way similar to how the MTA is used — but however, and this is the important part so listen up 📢, due to certain limitations in the hardware it is necessary to set all the hash bits to 1 and use the VMOLR ROPE bit as a promiscuous enable bit to allow vlan tag stripping when promiscuous mode is enabled 😭💀

like yeah. that's the whole deal. all hash bits to 1, VMOLR ROPE bit doing promiscuous-enable duty, and vlan tag stripping stays working while promiscuous mode is on. the hardware said "limitations" and we said "fine, periodt" 💅✨

first up, the source file bestie 🎀

  • Kernel file ./drivers/net/ethernet/intel/igb/igb_main.c

and then… the whole friend group 🫶 literally all of them, no skips:

like… the whole igb cinematic universe fr fr 🌈👑

lowkey a whole register-array moment, but you ate that 💅 go read your driver source bestie, it's all in ./drivers/net/ethernet/intel/igb/igb_main.c 🦋

and that's the page !! this cutie lives in ./drivers/net/ethernet/intel/igb and it's dated October 2026 🎀✨ bye bestie, mwah 💖🌸
