STRUCT VIRTCHNL2_RULE_ACTION(9)

💖 struct virtchnl2_rule_action(9) 💖

okay so bestie, welcome to the Kernel API Manual, section 9 🎀 — this one's about struct virtchnl2_rule_action(9), which is literally the struct representing a single action for a flow. yes. one action. one flow. she's a whole vibe and she's here to tell the hardware what to do with your packets 💅

---

✨ SYNOPSIS ✨

struct virtchnl2_rule_action {
    __le32 action_type;
    union {
      __le32 q_id;
      __le32 q_grp_id;
      __le32 ctr_id;
      __le32 mark_id;
      u8 reserved[8];
    } act_conf;
 };

like, look at her. action_type up top doing main character energy, and then act_conf is a whole union that shapeshifts depending on what kind of action you picked 🦋

🌸 Members 🌸

• action_type — this tells you what kind of action it is. peep enum virtchnl2_action_types for the menu of options, iykyk ✨
• act_conf — the union carrying the actual action payload, and which field you read depends entirely on action_type. no cap, it's giving "choose your own adventure" 💫

💜 act_conf.q_id

queue id to redirect the packets to. point the packets here, that's it, that's the whole job 🫶

💜 act_conf.q_grp_id

queue group id to redirect the packets to — same idea as q_id but a whole squad of queues instead of just one 👑

💜 act_conf.ctr_id

this one's for the count action, and it's lowkey the most interesting one 😭 so listen up fr fr:

• if the input value is 0xFFFFFFFF, the control plane assigns a brand new counter and hands the counter ID back to the driver ✨
• if the input value is not 0xFFFFFFFF, then it has to be an existing counter that was already given to the driver for an earlier flow — and then this flow will share that counter 🫶

💜 act_conf.mark_id

the value used to mark the packets. this is the mark action's whole thing, periodt 🎀

💜 act_conf.reserved

reserved for future use 🙈 — so hands off, she's not for you yet
