i40e_del_macvlan_filter(9)

👑 i40e_del_macvlan_filter 💅

okay so real talk — this page lives in the Kernel API Manual, section 9, and it's giving "tiny function, enormous friend group" energy. Bestie, it deletes exactly one thing and then points you at like three hundred siblings. iconic behavior honestly. let's get into it 🎀

---

🌸 NAME 🌸

• i40e_del_macvlan_filter — ngl the one-line summary in the source is literally empty, so the honest vibe is: it deletes a mac filter on the channel VSI that serves as the macvlan. no cap, that's the whole personality 💖

---

✨ SYNOPSIS ✨

int i40e_del_macvlan_filter (struct i40e_hw *hw , u16 seid , const u8
*macaddr , int *aq_err );

(yes the spacing is exactly like that, we don't touch it, we respect it 🫶)

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure. the main character of this whole friend group tbh 👑
• seid — the seid of the channel VSI. it's a u16, it's important, it's the address of the vibe check 💫
• macaddr — the mac address to apply as a filter. literally the mac in question, const u8 *, hands off 🌸
• aq_err — store the admin Q error in here. int *, so it writes back at you, lowkey rude but useful 😭

---

💜 DESCRIPTION 💜

so what does it actually do? it deletes a mac filter on the channel VSI which serves as the macvlan. that's it. that's the whole gig. returns 0 on success — zero is the good ending, we love a zero 🎉

no tricks, no secret modes, no surprise behaviour. it just... deletes the filter. slay, honestly. periodt ✨
