ENUM OVS_SAMPLE_ATTR(9)

💖 enum ovs_sample_attr 💖

okay bestie so this one's from the Kernel API Manual and it's literally the page for enum ovs_sample_attr — no cap, that's the whole vibe. Let's get into it ✨

---

🎀 NAME 🎀

enum ovs_sample_attr — the attributes for the %OVS_ACTION_ATTR_SAMPLE action. That's it, that's the whole thing 💅

---

🦋 SYNOPSIS 🦋

enum ovs_sample_attr {
    OVS_SAMPLE_ATTR_PROBABILITY ,
    OVS_SAMPLE_ATTR_ACTIONS ,
    OVS_SAMPLE_ATTR_ARG

};

---

🌸 DESCRIPTION 🌸

So the way this works is: it executes the specified actions with the given probability on a per-packet basis. And nested actions will be able to access the probability value of the parent OVS_ACTION_ATTR_SAMPLE. Iconic behaviour honestly 🫶

✨ Constants ✨

• OVS_SAMPLE_ATTR_PROBABILITY — a 32-bit fraction of packets to sample with OVS_ACTION_ATTR_SAMPLE. Like, a value of 0 samples no packets at all, a value of UINT32_MAX samples literally all the packets, and the intermediate values sample intermediate fractions of packets. Math slay 💅
• OVS_SAMPLE_ATTR_ACTIONS — the set of actions to execute in a sampling event. These actions get passed as nested attributes. Lowkey nesting queen 🧚
• OVS_SAMPLE_ATTR_ARG — for in-kernel use, passing struct sample_arg derived from other attributes. iykyk 💜
