💖 ice_fltr_add_eth(9) 💖

okay so bestie, welcome to the manual page for ice_fltr_add_eth from the Kernel API Manual ✨ — yes it's a kernel function, yes it's that girl, and yes we're gonna get through it together 🫶

---

🌸 NAME 🌸

ice_fltr_add_eth — add specyfic ethertype filter

(and yes, "specyfic" is exactly how it's spelled up there, no cap, we're keeping it 💅 — the kernel said what it said)

---

✨ SYNOPSIS ✨

int ice_fltr_add_eth (struct ice_vsi *vsi , u16 ethertype , u16 flag ,
       enum ice_sw_fwd_act_type action );

that return type is int, just so we're clear from the jump 🔥

---

🦋 ARGUMENTS 🦋

• vsi — pointer to VSI struct 💜 like, this is the lil struct you're pointing at, that's the whole vibe
• ethertype — ethertype of filter 🎀 which filter are we talking about, ethertype-wise
• flag — direction of packet to be filtered, Tx or Rx 🌈 so pick a lane: transmit or receive, those are your two options
• action — action to be performed on filter match ⭐ what should go down the moment the filter matches, that's what this one's for

👑 SEE ALSO 👑

• Kernel file ./drivers/net/ethernet/intel/ice/ice_fltr.c — the literal source file, go read it, it ate 💅
