ENUM OVS_PSAMPLE_ATTR(9)

💅 enum ovs_psample_attr(9) — the Kernel API Manual moment

okay so bestie, welcome to this page from the Kernel API Manual, and no, it's not scary, it's literally just one little enum that tells your packet where to go get sampled. iykyk. let's get into it 🫶

---

✨ NAME ✨

enum ovs_psample_attr — the attrs for the %OVS_ACTION_ATTR_PSAMPLE action. that's it, that's the vibe check 👑

---

🦋 SYNOPSIS 🦋

here's the whole thing, no crumbs:

enum ovs_psample_attr {
    OVS_PSAMPLE_ATTR_GROUP ,
    OVS_PSAMPLE_ATTR_COOKIE

};

two members. two. and they're both serving 🎀

---

🌸 Constants 🌸

• OVS_PSAMPLE_ATTR_GROUP — a 32-bit number that IDs where the sample came from. it's giving "who sent me" energy, honestly 💅
• OVS_PSAMPLE_ATTR_COOKIE — an optional variable-length binary cookie stuffed with user-defined metadata. the max length is OVS_PSAMPLE_COOKIE_MAX_SIZE bytes, so don't go overboard bestie, it WILL cap you 😭

---

🔥 Description 🔥

okay so basically: it sends the packet to the psample multicast group with whatever group and cookie you specified. iconic behaviour, no notes.

and the fun part? you can combine this action with the OVS_ACTION_ATTR_TRUNC action to limit the size of the sample. obsessed — cap the sample, keep the drama small 🌈
