STRUCT IDPF_VPORT_CONFIG(9)

💅 struct idpf_vport_config(9) — the Kernel API Manual moment

okay bestie, welcome to the Kernel API Manual entry for struct idpf_vport_config(9), and no cap this one is a whole vibe — it's the struct that holds all the configuration data for a vport 🦋

---

✨ NAME ✨

struct idpf_vport_config — literally just vport configuration data. that's the whole assignment, and it ate 💅

---

🎀 SYNOPSIS 🎀

struct idpf_vport_config {
    struct idpf_vport_user_config_data user_config;
    struct idpf_vport_max_q max_q;
    struct idpf_queue_id_reg_info qid_reg_info;
    spinlock_t mac_filter_list_lock;
    spinlock_t flow_steer_list_lock;
    unsigned long flags[BITS_TO_LONGS( IDPF_VPORT_CONFIG_FLAGS_NBITS)];
};

look at her. six fields, all iconic, all doing their little jobs 🌸

🧚 Members 🧚

so here's the member-by-member vibe check, bestie — nothing skipped, promise 🤞

• user_config — head straight to struct idpf_vport_user_config_data for this one, it's giving "see the other page" energy, iykyk 💜
• max_q — the maximum possible queues. the ceiling. the limit. the "don't ask for more than this" 🍓
• qid_reg_info — struct to store the queue ID and register info. very organized, very demure, very mindful ✨
• mac_filter_list_lock — the lock whose entire personality is protecting the mac filters 🫶
• flow_steer_list_lock — same but for the fsteer filters. twin energy, no cap 💫
• flags — go look at enum idpf_vport_config_flags 👑 (yes, it's in SEE ALSO, we'll get there bestie)

ngl bestie, these locks are spinlocks — treat them with the respect they deserve or the kernel will simply end you 💀
