FUNCTION::IPMIB_FILT(3stap)

💖 FUNCTION::IPMIB_FILT — SNMP Information Tapset 💖

okay bestie, welcome to the ipmib corner of the SNMP Information Tapset, this is gonna be quick and cute, i promise 🫶

---

✨ NAME ✨

function::ipmib_filter_key — the default filter function for ipmib.* probes, no cap 💅

---

🌸 SYNOPSIS 🌸

ipmib_filter_key:long(skb:long,op:long,SourceIsLocal:long)

look at her. three args, one long out. she's serving function signature realness ✨

---

🎀 ARGUMENTS 🎀

• skb — a pointer to the struct sk_buff, literally just handing you the packet so you can peek at it 🦋
• op — the value that gets counted if the skb passes the filter, so like, the lil number that only shows up when your packet survives the vibe check 👑
• SourceIsLocal — 1 means it's a local operation, 0 means it's a non-local operation. that's it, that's the whole mood 🍓

---

💫 DESCRIPTION 💫

so this one is a default filter function, meaning she's the fallback girlie 🧚 the user is fully allowed to swap her out and drop in their own custom function instead — main character energy, honestly.

the user-supplied filter function returns an index key based on the values chilling inside skb. that's the whole job. index key. based on skb values. periodt.

⚠️ important, bestie: if the return value is 0, that means this particular skb should not be counted. like, she's off the guest list. don't count her. 😭
